Supported combinations: | Network | Asset | Balance credited | | ------- | ------ | ---------------- | | `tron` | `usdt` | USDT | | `eth` | `usdt` | USDT | | `eth` | `usdc` | USDC | | `btc` | `btc` | BTC | Every deposit credits the **balance of its own asset** (a USDC wallet credits your USDC balance; the Bitcoin wallet credits your BTC balance). `GOLD` is the only balance with no on-chain rail: it moves only via internal transfers and operator credits. ```mermaid theme={"theme":{"light":"github-light","dark":"github-dark"}} flowchart LR subgraph depositFlow [Deposit] wallet["Your CBPay wallet

Deposit wallets are **entry doors**, not operating wallets: they only **receive** crypto that credits your virtual balance. They cannot send funds, and cannot be exported or imported (that is what [segregated wallets](/en/guides/segregated-wallets) are for). Two products, two routes: deposit wallets live under `/v1/crypto/wallets` and segregated wallets under `/v1/segregated-wallets`. Every wallet response carries a `type` discriminator (`deposit` / `segregated`) so you can always tell them apart. | Account type | Deposit wallets per network+asset pair | | ------------ | ----------------------------------------------- | | Person | **1** (the birth wallets already take the slot) | | Company | **1** (the birth wallets already take the slot) | ## Can I create more deposit wallets? No. Every account — person and company — holds exactly **one deposit wallet per network+asset pair**, and all of them are born with the account. `POST /v1/crypto/wallets` exists only to restore a missing pair (an exceptional case): with the four wallets already provisioned it responds `422 wallet_limit_reached`. ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/wallets \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "eth", "asset": "usdc" }' ``` With the pair already provisioned — `422`: ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "error": "wallet_limit_reached", "message": "accounts hold one deposit wallet per network/asset pair (created automatically with the account); use segregated wallets for additional wallets" } ``` * Birth wallets are **always free**; the `wallet_creation` fee would only apply to a manual restoration (with a fee of 0, the default, it is free; if creation fails, the charge is refunded automatically). * Need **several wallets** with their own balance (per client, per project, per business unit)? That is the [segregated wallets](/en/guides/segregated-wallets) product: companies have no limit, persons hold 1 per network+asset pair. ## View my wallets ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} curl https://api.qbank.cl/platform/v1/crypto/wallets \ -H "Authorization: Bearer " ``` ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "wallets": [ { "wallet_id": "b7e3…", "chain": "tron", "asset": "USDT", "address": "TQmZ…", "label": "", "type": "deposit", "receive_only": true, "created_at": "2026-07-07T12:00:00Z" }, { "wallet_id": "a1c9…", "chain": "eth", "asset": "USDT", "address": "0x8f3B…", "label": "", "type": "deposit", "receive_only": true, "created_at": "2026-07-07T12:00:00Z" }, { "wallet_id": "fb88…", "chain": "eth", "asset": "USDC", "address": "0xa072…", "label": "", "type": "deposit", "receive_only": true, "created_at": "2026-07-07T12:00:00Z" }, { "wallet_id": "c1d4…", "chain": "btc", "asset": "BTC", "address": "bc1qf66…", "label": "", "type": "deposit", "receive_only": true, "created_at": "2026-07-07T12:00:00Z" } ] } ``` Bitcoin addresses are **native bech32** (`bc1q…`): any modern wallet or exchange can send funds to them. BTC amounts use 8 decimals (`"0.00050000"`). ## Deposit Send the wallet's asset to its address, **over the correct network**. When the deposit confirms on-chain, that asset's balance is credited automatically (net of the `funding` fee if CBPay configured one) and the `crypto_deposit_credited` webhook fires: ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "account_id": "…", "chain": "tron", "asset": "USDT", "tx_id": "b1946ac9…", "amount": "499.000000", "fee": "1.000000" } ``` Send **only the wallet's asset over its network** (USDT to a USDT wallet, USDC to a USDC wallet, BTC to the Bitcoin wallet). Addresses are yours and stable: you can reuse them for every deposit. ### Confirmation times | Network | Detection | Credit (network confirmation) | | -------- | ----------------------------- | ----------------------------------------- | | TRON | Near-instant | **\~1 minute** (19 confirmations) | | Ethereum | Near-instant | **A few minutes** depending on congestion | | Bitcoin | At the first block (\~10 min) | **\~30 minutes** (3 confirmations) | The credit always arrives with the webhook and the `tx_id` so you can verify it on the network explorer. ## Transfer (on-chain withdrawals) Send USDT, USDC or BTC from its balance to any external address (`asset` is optional: default `USDT` on `tron`/`eth` and `BTC` on `btc`; USDC only over `eth`): ```bash USDT over TRON theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/withdrawals \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "tron", "to_address": "TVJ6…", "amount": "100.000000", "idempotency_key": "withdrawal-2026-07-07-b" }' ``` ```bash USDC over Ethereum theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/withdrawals \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "eth", "asset": "USDC", "to_address": "0x8f3B…", "amount": "50.000000", "idempotency_key": "withdrawal-usdc-2026-07-09-a" }' ``` ```bash BTC over Bitcoin theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/withdrawals \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "btc", "to_address": "bc1qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4", "amount": "0.00050000", "idempotency_key": "withdrawal-btc-2026-07-15-a" }' ``` On Bitcoin the destination can be a bech32 (`bc1q…`), taproot (`bc1p…`) or legacy (`1…` / `3…`) address. The Bitcoin **network fee** is covered by the operation itself — you receive the final status via webhook like any other withdrawal. Response `202` — `amount + fee` is debited and the transaction broadcasts: ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "withdrawal_id": "5e8c…", "chain": "tron", "asset": "USDT", "to_address": "TVJ6…", "amount": "100.000000", "fee": "1.000000", "total_debit": "101.000000", "status": "processing", "tx_id": "…" } ``` Every withdrawal saves the address as a [contact](/en/guides/contacts) automatically — name it with `"contact_name"` in the body, or disable it with `"save_contact": false`. To repeat a send, use `"to_contact_id"` instead of `to_address` (the contact's saved address for that `chain` is used). The final state arrives via the `crypto_withdrawal_status_changed` webhook: **`completed`** (the `tx_id` is your receipt) or **`failed`** (the full debit is refunded). You can also query the withdrawal at any time: ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} curl https://api.qbank.cl/platform/v1/crypto/withdrawals/5e8c… \ -H "Authorization: Bearer " ``` ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "withdrawal_id": "5e8c…", "chain": "tron", "asset": "USDT", "to_address": "TVJ6…", "amount": "100.000000", "fee": "1.000000", "total_debit": "101.000000", "status": "completed", "status_code": "confirmed", "status_message": "confirmed on-chain", "tx_id": "7d1f…" } ``` To move balance to **another CBPay account**, skip the blockchain: [internal transfers](/en/guides/transfers) are instant and free. ### Travel Rule (withdrawals above the threshold) International regulation (FATF R.16, the "Travel Rule") requires on-chain withdrawals **from 1,000 USD** to declare who receives the funds before moving the money. Below the threshold nothing changes. There are two paths: If the destination is a wallet owned by the account holder (not an exchange), declare `wallet_type` and the beneficiary name: ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/withdrawals \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "tron", "to_address": "TVJ6…", "amount": "1500.000000", "wallet_type": "self_hosted", "beneficiary_name": "Maria Perez", "idempotency_key": "withdrawal-2026-07-12-a" }' ``` The response includes `"travel_rule_status": "self_hosted_attested"`. If the destination is an account at another compatible institution, ask the beneficiary for their **travel address** (a code starting with `ta…`) and send it along with their name — the payment address is provided by the receiving institution, so `to_address` can be omitted: ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} curl -X POST https://api.qbank.cl/platform/v1/crypto/withdrawals \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "chain": "tron", "amount": "1500.000000", "travel_address": "ta2AQSjBotWQf38c8sxYYK2Kfis…", "beneficiary_name": "Maria Perez", "idempotency_key": "withdrawal-2026-07-12-b" }' ``` The exchange with the receiving institution happens inline. If it approves, the withdrawal goes to the address it provided and the response includes `"travel_rule_status": "approved"`. If the institution rejects (`travel_rule_rejected`) or has not resolved yet (`travel_rule_pending`), the withdrawal is not executed and nothing is debited — retry later with the **same** `idempotency_key`. | Error | What it means | What to do | | ---------------------------------- | ---------------------------------------------------------------------------------- | ------------------------------------------------------------------------- | | `travel_rule_required` | Withdrawal above the threshold without beneficiary data | Add `travel_address` or `wallet_type: "self_hosted"` + `beneficiary_name` | | `travel_rule_beneficiary_required` | `beneficiary_name` is missing | Send the destination holder's name | | `travel_rule_address_mismatch` | Your `to_address` does not match the address approved by the receiving institution | Omit `to_address` or use the address from the approved exchange | | `travel_rule_rejected` | The receiving institution rejected the transfer | Verify the beneficiary data with the recipient | | `travel_rule_pending` | The receiving institution has not resolved yet | Retry later with the same `idempotency_key` | | `travel_rule_unavailable` | Exchange temporarily unavailable | Retry with the same `idempotency_key` | ## Movements ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} # On-chain activity: deposits + withdrawals, with tx_id and date filters curl "https://api.qbank.cl/platform/v1/crypto/transactions?from=2026-07-01&to=2026-07-08" \ -H "Authorization: Bearer " ``` ```json theme={"theme":{"light":"github-light","dark":"github-dark"}} { "page": 1, "page_size": 50, "deposits": [ { "chain": "tron", "asset": "USDT", "tx_id": "b1946ac9…", "from_address": "TX9a…", "amount": "499.000000", "reference": "dep_8813…", "created_at": "2026-07-07T12:10:00Z" } ], "withdrawals": [ { "withdrawal_id": "5e8c…", "chain": "tron", "asset": "USDT", "to_address": "TVJ6…", "amount": "100.000000", "fee": "1.000000", "total_debit": "101.000000", "status": "completed", "tx_id": "7d1f…", "created_at": "2026-07-07T15:00:00Z" } ] } ``` ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} # Current balance (available + held) curl https://api.qbank.cl/platform/v1/balances \ -H "Authorization: Bearer " # Full accounting history (funding, withdrawals, wallet fees…) curl "https://api.qbank.cl/platform/v1/movements?type=funding&from=2026-07-01&to=2026-07-08" \ -H "Authorization: Bearer " ``` Every deposit credits the **balance of its wallet's asset** (USDT, USDC or BTC); wallets are entry points, each currency has a single balance. ## Errors | HTTP | `error` | Cause | | ---- | ---------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | | 400 | `invalid_chain` | Unsupported network (use `tron`, `eth` or `btc`) | | 400 | `invalid_asset` | Network/asset pair without an on-chain rail (supported: `tron`/`usdt`, `eth`/`usdt`, `eth`/`usdc`, `btc`/`btc` — `GOLD` does not operate on-chain) | | 400 | `to_address_required` | Missing withdrawal destination address | | 402 | `insufficient_funds` | Not enough balance in that asset (for the withdrawal or the creation fee) | | 422 | `wallet_limit_reached` | The account already holds its deposit wallet for that network+asset pair (applies to persons and companies) | | 422 | (withdrawal with `status: failed`) | Rejected at broadcast; debit refunded | | 503 | `withdrawals_unavailable` | Withdrawals not enabled for this corridor yet |
