Summary

  • Documents that SD (South Dakota) Trust is the team responsible for signing backing wallets under EVM cross-chain recovery, using the Singapore key shards
  • Clarifies that SG (Singapore) Custody does not sign directly and will not see a signing request in their reports
  • Documents required unsigned JSON fields (nextContractSequenceId, expireTime) needed before SD Trust can sign
  • Documents the halfSigned.txHex validation requirement to avoid broadcast failures

Test plan

  • No code logic changed — documentation and JSDoc only
  • Verify README renders correctly on GitHub
  • Confirm JSDoc comment is visible in abstractEthLikeNewCoins.ts at recoverEthLikeforEvmBasedRecovery

Ticket: CGD-1206

Document that SD (South Dakota) Trust is responsible for signing
backing wallets under EVM cross-chain recovery, using Singapore key
shards. SG Custody does not sign directly and should not receive
signing requests.

Also document required unsigned JSON fields (nextContractSequenceId,
expireTime) and the halfSigned.txHex validation requirement to
prevent ambiguity during recovery handling.
