* fallback to custom ethereum checksum validator -> https://github.com/go-playground/validator/issues/1073 * decouple jetsream emitter to separate package * refactor task handlers into individual files * add error handler for echo to capture unexpected errors and log them * move handler dependencies into single struct container -> custodialContainer * replace signer to use EIP 1559 signer -> celoutils v1 * Add 1 minutes timeout to all custodial tasks
