TRON: pre-flight simulation, status polling, verify-decode preview - #43
Merged
Conversation
- Pre-flight TRC-20 sends via /wallet/triggerconstantcontract — catches balance/blocklist/pause reverts at prepare time instead of on broadcast. - Populate estimatedEnergyUsed + estimatedEnergyCostSun from the dry-run so verify_tx_decode can frame fee_limit as a cap vs expected burn. - Extend get_transaction_status to TRON via TronGrid gettransactionbyid + gettransactioninfobyid. - Claim-rewards cooldown: surface remaining time (Xh Ym) from latest_withdraw_time when the 24h window hasn't elapsed. - verify_tx_decode on TRON now returns the decoded action preview + fee framing instead of a generic "EVM-only" fallback.

TRON blocks every ~3s; the uniform 5s poll interval added perceptible latency over the actual inclusion time. Split the cadence into a per-chain table: 3s/1min for TRON + L2s, 5s/2min for Ethereum L1. Undershooting the block time is fine — the node just returns "unknown" / "pending" on the extra polls.
