Bridge speed

Last updated: February 19, 2026

Overview

Rhino.fi supports three bridge speeds, which are specified in the API quote response:

  • Fast

  • Standard

  • Slow

Bridge speed determines how quickly a transaction is processed and credited on the destination chain.

The selected speed is determined automatically based on transaction parameters and cannot be manually specified by clients.

Standard Speed

Standard speed is the default bridge mode.

It applies across all supported chains and transaction sizes, subject to available liquidity and confirmation requirements.

Standard speed is determined by:

  • The number of required confirmations on the source chain

  • Available liquidity on the destination chain

If the requested amount exceeds available liquidity on the destination chain, the transaction will automatically revert to slow speed.

Typical completion time:
20–40 seconds

Fast Speed

Fast speed is available for transactions up to a defined threshold of $50,000.

In fast mode:

  • Rhino.fi requires fewer confirmations on the source chain

  • Processing may begin after as few as one confirmation

  • Crediting on the destination chain begins immediately

Fast speed is currently available when the source chain is an EVM network.

Typical completion time:
3–15 seconds

Slow Speed

Slow speed is used for:

  • Very large transfers

  • Transactions exceeding available liquidity on the destination chain

In these cases, Rhino.fi may need to rebalance liquidity from:

  • The source chain

  • Other supported chains with sufficient liquidity

Once the destination chain holds sufficient liquidity, the crediting transaction is executed.

Typical completion time:
8–20 minutes

What Determines Bridge Speed

Bridge speed depends on several factors, including:

  • Transaction amount

  • Required confirmation depth

  • Available liquidity on the destination chain

Clients cannot manually select bridge speed.

API Fields

The quote response includes:

  • speed — A human-readable value (fast / standard / slow)

  • estimatedDuration — The estimated time to completion, expressed in milliseconds

These fields allow clients to inform users about expected settlement time before executing a transaction.

Smart Deposit Address (SDA) Speed Considerations

Smart Deposit Address transactions conform to the same bridge speed constraints described above (fast, standard, slow).

However, the infrastructure required to monitor and detect SDA deposits may influence overall completion time.

Rhino.fi monitors a large number of Smart Deposit Addresses across multiple chains using a combination of:

  • Third-party RPC providers

  • Webhook-based event listeners

  • A bespoke interval-based monitoring system

For all EVM chains and Solana, the primary monitoring mechanism is webhook-based. This enables near-instant deposit detection under normal conditions. A secondary interval-based scan runs periodically to ensure no events are missed.

For Tron, SDA monitoring relies exclusively on a proprietary sync model built by Rhino.fi.

Depending on chain conditions and monitoring triggers, these processes may add up to approximately 30 seconds to overall processing time.

Rhino.fi continuously optimizes this infrastructure, with the objective of reducing SDA transaction finality to a practical minimum while maintaining reliability and accuracy.
