Cross-chain atomic swap
Hash time lock contract or HTLC is a composition of a hash lock and a time lock. The hash lock authorizes the ClaimHTLC transaction. The time lock authorizes the RefundHTLC transaction. The result of this contract is either success or refund, assuming that transactions are timely included to the blockchain. It is also named an atomic swap.
Hash lock
Hash lock is a cross-chain authorization mechanism that requires a preimage of a cryptographic hash.
- BLAKE2b-256
- SHA-256
- Keccak-256
- RIPEMD-160
Time lock
Time lock is a cross-chain authorization mechanism that requires a specified block time or height to pass.
- Absolute block time
- Absolute block height
- Relative block time
- Relative block height
RPC API
In version 0.3 RPC API will be implemented.
