Frequently asked questions
- What does 1Sec bridge?
- ICP and Bitcoin (ckBTC) to Base, Arbitrum, and Ethereum. The ICP side is gas-free; destination chain fees apply.
- How long does a bridge take?
- Typically under a minute. Chain-key cryptography handles the signing, so there's no multi-block confirmation wait.
- Is 1Sec third-party?
- No. Bridging uses the Internet Computer's chain-key cryptography — the subnet signs transactions directly, with no centralized custodian holding funds.
