Withdraw From Zebec

Withdraw from vault to proxy accounts

At first, you have to withdraw your assets from the Zebec. To withdraw you can do as follows.

const withdrawer = signer.address

const withdrawerAddrInSolana = ZebecSolBridgeClient.getProxyUserKey(
   withdrawer,
   sourceChain,
   SOL_ZEBEC_BRIDGE_ADDRESS,
);

const tokenAddrInSolana = "<solana mint key>";
const amount = "1";

const reciept = await ethClient.withdraw(amount, withdrawer, tokenAddrInSolana);

Now you can find signed Vaa bytes of your payload sent from wormhole guardian rpc hosts.

const sequence = parseSequenceFromLogEth(
   receipt, 
   getBridgeAddressForChain(sourceChain)
);
const zebecEmitterAddress = getEmitterAddressEth(BSC_ZEBEC_BRIDGE_ADDRESS);
const { vaaBytes } = await getSignedVAAWithRetry(
   WORMHOLE_RPC_HOSTS, 
   sourceChain, 
   zebecEmitterAddress, 
   sequence
);

Now post this signed vaa to wormhole solana core bridge program, parse the payloads from vaa and send the parsed data to solana zebec bridge program. Posting vaa and calling solana bridge (also called as proxy) program. This is optional because it's handled by zebec's specialized relayer.

const payerAddress = wallet.publicKey.toString();

const bridgeAddress = getBridgeAddressForChain(targetChain);
const tokenBridgeAddress = getTokenBridgeAddressForChain(targetChain);
const vaaBuf = Buffer.from(vaaBytes);

setDefaultWasm("node"); // use bundler for browser
const { parse_vaa } = await importCoreWasm();

// posting vaa in solana
await postVaaSolanaWithRetry(
   connection,
   wallet.signTransaction,
   bridgeAddress,
   payerAddress,
   vaaBuf,
   MAX_VAA_UPLOAD_RETRIES_SOLANA,
);

const { parse_vaa } = await importCoreWasm();
const parsedVaa = parse_vaa(tes)
const parsedPayload = parseZebecPayload(Buffer.from(parsedVaa.payload));

const result = await solanaClient.withdrawDeposit(withdrawVaa, parsedPayload as TokenWithdrawPayload);
