Adding aptos service implementation

No description provided.

General approach: Remove or obfuscate the logging of the potentially sensitive authKey-derived address (addr.String()) while preserving existing behavior of the method. We do not need to change how addresses are computed or used, only how they are logged.

Best concrete fix: In relayer/aptos_service.go, within getAccountWithHighestBalance, modify the Warnw call in the error path for client.AccountAPTBalance so that it no longer logs addr.String(). The rest of the message, including the account identifier and the error, can remain as-is to preserve debuggability. Since removing a structured log field is backwards-compatible (callers of this code do not consume logs programmatically), this does not alter functional behavior of the relayer.

Changes needed:

• File relayer/aptos_service.go:
  • At line 201, update the Warnw invocation to drop the "address", addr.String() key/value pair.
  • No additional imports, methods, or definitions are required.

To fix the problem, we should ensure that the potentially sensitive value (fromAddress) is not logged in clear text. The simplest way to do this without changing functional behavior is to either (1) remove the "fromAddr" field from the log entirely, or (2) log only a non-sensitive, obfuscated form (e.g., a truncated address or a stable hash) that still supports debugging without exposing the full address.

The single best minimally invasive fix here is to remove or anonymize the logged address at the debug line in EnqueueCRE in relayer/txm/txm.go. Since the transaction ID is already part of the contextual logger (GetContexedTxLogger), and the tx object contains the FromAddress stored in memory for later use, logging the full fromAddress is not necessary. We can change:

ctxLogger.Debugw("Tx enqueued", "fromAddr", fromAddress)

either to:

ctxLogger.Debugw("Tx enqueued")

or to an obfuscated form like:

ctxLogger.Debugw("Tx enqueued", "fromAddr_suffix", fromAddress[len(fromAddress)-6:])

if you still want some address context. To stay conservative and avoid even partial leakage, the cleanest fix is to remove the address field entirely.

Concretely:

• File: relayer/txm/txm.go
• In EnqueueCRE, modify the Debugw call in the case a.broadcastChan <- transactionID: branch to stop including fromAddress.
• No new imports or helpers are required for the “remove field” approach.
