NewCoinSwap

NewCoinSwap creates a new atomic swap contract for native coins. It uses a default timelock duration.

NewGRC20Swap

NewGRC20Swap creates a new atomic swap contract for grc20 tokens. It uses gno.land/r/demo/defi/grc20reg to lookup for a registered token.

NewCustomCoinSwap

NewCoinSwapWithTimelock creates a new atomic swap contract for native coin. It allows specifying a custom timelock duration. Only direct user-call (maketx call) is accepted: unsafe.OriginSend() describes a real receipt at this realm only when the caller is a pure EOA. Intermediate code realms or \`maketx run\` ephemeral realms can attach -send to the tx but spend the envelope elsewhere, leaving OriginSend() describing a phantom payment that would let the swap drain the realm's pre-existing balance on Claim.

NewCustomGRC20Swap

NewCustomGRC20Swap creates a new atomic swap contract for grc20 tokens. It is not callable with \`gnokey maketx call\`, but can be imported by another contract or \`gnokey maketx run\`.

Claim

Claim allows the recipient to claim the funds if they provide the correct preimage. rlm is the cur of the surrounding crossing wrapper; rlm.Previous() is the immediate caller of that wrapper, against which we authorize.

Refund

Refund allows the sender to refund the funds after the timelock has expired.

Render

Render returns a list of swaps (simplified) for the homepage, and swap details when specifying a swap ID.

require

require checks a condition and panics with a message if the condition is false.

mustGet

mustGet retrieves a swap by its id or panics.

Swap

Swap represents an atomic swap contract.
