worker

Documentation

Overview

Package worker includes all the tasks and jobs to process router swaps.

It contains the following main steps (concurrently):

verify
	verify registered swaps.
swap
	build swaptx, mpc sign the tx, and send the tx to blockchain.
accept
	the `oracle` node do the accept job, agree or disagree the signing after verifying by oralce itself.
stable
	mark swap status to `stabe` status.
replace
	replace swap with the same tx nonce value when the sent swaptx is not packed into block because of lack fee or other reasons.
passbigvalue
	pass big value swap if the swap value is too large.

Most the above jobs is assigned to the `server` node, the `oracle` node mainly do the `accept` job.
