Native Bitcoin SDAs

Last updated: September 8, 2026

Native Bitcoin support

Rhino.fi Smart Deposit Addresses accept native Bitcoin. A customer can send BTC directly, and it settles into whatever supported chain and token with optional Automated Onchain Action capability. No new integration is required: Bitcoin behaves like any other supported chain within the existing SDA flow.

How it works

Generate a Smart Deposit Address the same way as for any other chain, including BITCOIN in depositChains array. Once a customer sends native BTC to that address, Rhino.fi settles it into the destination configured for that address. BTC SDAs are reusable. Examples:

  • Settle to a wrapped BTC position — via a Post Bridge Action, deposited BTC can be delivered as a wrapped BTC token directly into a destination contract, such as a vault.

  • Settle to another supported asset — set tokenOut on the deposit address to automatically convert the deposited BTC into USDC, USDT, EURC or any other Rhino.fi-supported asset, on any supported destination chain.

The same KYT/AML compliance screening applies to Bitcoin deposits as to every other Rhino.fi route.

Speed

A Bitcoin deposit is processed after one network confirmation. Confirmation time depends on Bitcoin network conditions and is outside Rhino.fi's control.

Limits

  • Minimum deposit: 5,000 sats (0.00005 BTC). Rhino.fi surfaces a $10 minimum in the API but amounts under $10 will be credited as long as the deposit is above 5000sats.

  • Maximum deposit: $50,000 per transaction at launch. The current limit is always available via the configuration endpoint (GET /bridge/configs/chains-and-tokens), and is expected to rise as the route matures. Deposits above this limit are still processed, but may receive a less favourable settlement rate on the amount above it. Higher limits can be requested — contact your Rhino.fi account manager.

Fees

Native Bitcoin deposits are charged at $1 per deposit, as part of the Tron, Solana and Bitcoin Extension. See Tron, Solana and Bitcoin Extension for how this is billed.

Rhino.fi locks the rate one the deposit is confirmed on the Bitcoin blockchain as long as the deposit in BTC is within the current min and max deposit limits. The actual limit value can be determined via API at any time.

Constraints

  • Currently one-directional: native BTC deposits settle into other supported assets. Converting other assets back into native BTC is not yet supported.

  • As with all SDAs, users should be shown the applicable minimum and maximum deposit values before initiating a transaction.

Enabling Bitcoin on your account

Native Bitcoin deposit support is being rolled out client by client. Contact your Rhino.fi account manager to enable it for your integration.
