SDK: track older FastBridge transactions

[ChiTimesChi]

In the current implementation, only the txs done through the latest FastBridge contracts are trackable using the exposed SDK methods:

• getSynapseTxId()
• getBridgeTxStatus()

This should be fixed to support all historical FastBridge deployments for backwards compatibility.

To support historical FastBridge deployments in the SDK methods getSynapseTxId and getBridgeTxStatus, follow these steps:

1. Update getSynapseTxId method in fastBridgeRouter.ts:

   • Modify the method to iterate through all historical FastBridge contract addresses.
   • Example:

   public async getSynapseTxId(txHash: string): Promise<string> {
     const fastBridgeContracts = await this.getAllFastBridgeContracts();
     for (const fastBridgeContract of fastBridgeContracts) {
       try {
         const fastBridgeLog = await getMatchingTxLog(
           this.provider,
           txHash,
           fastBridgeContract,
           this.originEvents
         );
         const parsedLog = fastBridgeContract.interface.parseLog(fastBridgeLog);
         return parsedLog.args.transactionId;
       } catch (e) {
         // Continue to next contract if no matching log is found
       }
     }
     throw new Error('Transaction ID not found');
   }

2. Update getBridgeTxStatus method in fastBridgeRouter.ts:

   • Modify the method to check the status across all historical FastBridge contract addresses.
   • Example:

   public async getBridgeTxStatus(synapseTxId: string): Promise<boolean> {
     const fastBridgeContracts = await this.getAllFastBridgeContracts();
     for (const fastBridgeContract of fastBridgeContracts) {
       try {
         const status = await fastBridgeContract.bridgeRelays(synapseTxId);
         if (status) return true;
       } catch (e) {
         // Continue to next contract if status is not found
       }
     }
     return false;
   }

3. Implement getAllFastBridgeContracts method in fastBridgeRouter.ts:

   • This method should return an array of all FastBridge contract instances.
   • Example:

   private async getAllFastBridgeContracts(): Promise<FastBridgeContract[]> {
     const addresses = [
       '0x5523D3c98809DdDB82C686E152F5C58B1B0fB59E', // Add all historical addresses here
       // ... other addresses
     ];
     return addresses.map(address => new Contract(
       address,
       FastBridgeRouter.fastBridgeInterface,
       this.provider
     ) as FastBridgeContract);
   }

Hi @trajan0x is this taken or stale ?
