Create a commitment

Call the commit() function to lock funds for a specified party with a timelock of $T + \beta$ .

Monitor the destination chain

Watch for the TokenLocked event or use the Id on the destination chain by calling getDetails().
Verify that the hashlock of the HTLC on the destination chain provides sufficient time to act, ensuring it is at least $T + 2\Delta$ .
Once detected, capture the hashlock value.

The state of the destination chain should be read from a Light Client if one exists; if not, it should be read from multiple RPC providers.

Add lock to your PreHTLC on the source chain

Call addLock(), passing in the captured hashlock and timelock of $T + \Delta$ .

(signature flow) Sign a message instead of adding a lock

The user signs a message containing the Id, hashlock, and timelock.

If funds are not released on the destination chain, watch the source chain for the TokenRedeemed event (or getDetails() function).
Once detected, capture the secret and call redeem() on the destination chain.
