Deposit to Zebec

Deposit from solana account to zebec vaults

Depositing token from proxy accounts to zebec vault can be done in following way. You first need to pass message to solana chain using evm bridge contracts for deposit tokens.

const tokenAddress = "0xea0Fbe70025ac7Cab1F5f06976dA76Ac85C045d9";
const tokenAddressSol = await getTargetAsset(signer, tokenAddress, sourceChain, targetChain);

// deposit same amoutn of token that you migrated from bsc to solana 
const receipt = await ethClient.deposit(amount, depositor, tokenAddrInSolana);

Then the vaa can be obtained after this and which'll be posted in solana chain.

const sequence = parseSequenceFromLogEth(receipt, getBridgeAddressForChain(sourceChain));
const emitterAddress = getEmitterAddressEth(BSC_ZEBEC_BRIDGE_ADDRESS);
const { vaaBytes } = await getSignedVAAWithRetry(
	WORMHOLE_RPC_HOSTS,
	sourceChain,
	emitterAddress,
	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 vaaBuf = Buffer.from(vaaBytes);

setDefaultWasm("node"); // use bundler for browser

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

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

const depositResult = await solClient.depositToken(depositVaa, depositPayload);
