} lastBlockSynced = 7089137
lastKnownBlock = 1008
lastBlockSynced为L1数据，lastKnownBlock为L2数据，说明s.etherMan应使用L1 RPC，目前使用了L2RPC导致出错
s.storage.GetLastBlock查询时有networkID区分，所以被对比数据是正确的
s.networkID等于0， s.etherMan使用的L2 RPC, 也就是networkID与etherMan对应关系乱了
func runSynchronizer(ctx context.Context, genBlockNumber uint64, brdigeCtrl *bridgectrl.BridgeController, etherman *etherman.Client, cfg synchronizer.Config, storage db.Storage, zkEVMClient *client.Client, chExitRootEventL2 chan *etherman.GlobalExitRoot, chsExitRootEvent []chan *etherman.GlobalExitRoot, chSynced chan uint, allNetworkIDs []uint) {

}

}for i, l2EthermanClient := range l2Ethermans {
log.Debug("trusted sequencer URL ", c.Etherman.L2URLs[i])

go runSynchronizer(ctx.Context, 0, bridgeController, l2EthermanClient, c.Synchronizer, storage, zkEVMClient, chExitRootEventL2, nil, chSyncedL2, []uint{})
}
chSynced := make(chan uint)
go runSynchronizer(ctx.Context, c.NetworkConfig.GenBlockNumber, bridgeController, l1Etherman, c.Synchronizer, storage, nil, nil, chsExitRootEvent, chSynced, networkIDs)
func newEthermans(c *config.Config) (*etherman.Client, []*etherman.Client, error) {
l1Etherman, err := etherman.NewClient(c.Etherman,
c.NetworkConfig.PolygonBridgeAddress,
c.NetworkConfig.PolygonZkEVMGlobalExitRootAddress,
c.NetworkConfig.PolygonRollupManagerAddress)
if err != nil {
log.Error("L1 etherman error: ", err)
return nil, nil, err
}
if len(c.L2PolygonBridgeAddresses) != len(c.Etherman.L2URLs) {
log.Fatal("environment configuration error. zkevm bridge addresses and zkevm node urls mismatch")
}
var l2Ethermans []*etherman.Client
for i, addr := range c.L2PolygonBridgeAddresses {
l2Etherman, err := etherman.NewL2Client(c.Etherman.L2URLs[i], addr, c.NetworkConfig.L2ClaimCompressorAddress)
if err != nil {
log.Error("L2 etherman ", i, c.Etherman.L2URLs[i], ", error: ", err)
return l1Etherman, nil, err
}
l2Ethermans = append(l2Ethermans, l2Etherman)
}
return l1Etherman, l2Ethermans, nil
}对于l1Etherman networkID直接没有赋值，所以等于0
func NewClient(cfg Config, polygonBridgeAddr, polygonZkEVMGlobalExitRootAddress, polygonRollupManagerAddress common.Address) (*Client, error) {
logger := log.WithFields("networkID", 0)
// Connect to ethereum node
ethClient, err := ethclient.Dial(cfg.L1URL)对于l2Etherman，经过NewL2Client
func NewL2Client(url string, polygonBridgeAddr, claimCompressorAddress common.Address) (*Client, error) {
// Connect to ethereum node
ethClient, err := ethclient.Dial(url)
if err != nil {
log.Errorf("error connecting to %s: %+v", url, err)
return nil, err
}
// Create smc clients
bridge, err := polygonzkevmbridge.NewPolygonzkevmbridge(polygonBridgeAddr, ethClient)
if err != nil {
return nil, err
}
oldpolygonBridge, err := oldpolygonzkevmbridge.NewOldpolygonzkevmbridge(polygonBridgeAddr, ethClient)
if err != nil {
return nil, err
}
var claimCompressor *claimcompressor.Claimcompressor
if claimCompressorAddress == (common.Address{}) {
log.Warn("Claim compressor Address not configured")
} else {
log.Infof("Grouping claims allowed, claimCompressor=%s", claimCompressorAddress.String())
claimCompressor, err = claimcompressor.NewClaimcompressor(claimCompressorAddress, ethClient)
if err != nil {
log.Errorf("error creating claimCompressor: %+v", err)
return nil, err
}
}
networkID, err := bridge.NetworkID(&bind.CallOpts{Pending: false}) // 从合约读取
if err != nil {
return nil, err
}
scAddresses := []common.Address{polygonBridgeAddr}
logger := log.WithFields("networkID", networkID)
return &Client{
logger: logger,
EtherClient: ethClient,
PolygonBridge: bridge,
OldPolygonBridge: oldpolygonBridge,
SCAddresses: scAddresses,
ClaimCompressor: claimCompressor,
NetworkID: networkID,
}, nil
}对于L2 会使用对应的L2 RPC从二层桥合约读取对应的NetworkID
// Solidity: function networkID() view returns(uint32)
func (_Polygonzkevmbridge *PolygonzkevmbridgeCaller) NetworkID(opts *bind.CallOpts) (uint32, error) {
var out []interface{}
err := _Polygonzkevmbridge.contract.Call(opts, &out, "networkID")
if err != nil {
return *new(uint32), err
}
out0 := *abi.ConvertType(out[0], new(uint32)).(*uint32)
return out0, err
}查询二层networkID，确实是0
目前的问题就是因为二层桥合约错误的设置了networkID，导致逻辑错乱，进一步分析下，二层networkID什么时候设置的，如何导致的错误
经过确认，PolygonZkEVMBridgeV2合约没有初始化
结论
经过确认和重置对比测试，该错误是因为当时部署时RPC不稳定造成的交易丢失，所以部署时尽量选择稳定的RPC以及对应链相对空闲时段部署，并且部署完成后检查一下L2的networkID是否为1
