EVM Withdraw

Queue a withdrawal of vault shares from DeFi protocols (currently Veda vaults). Unlike immediate redemptions, withdrawals enter a processing queue managed by the protocol.

Important Notes

Only one withdrawal request can be active at a time per address
Submitting a new withdrawal request replaces the existing one — amounts are updated, not added
Minimum withdrawal: 0.00010001 vault shares

Supported Networks

Production: Ethereum, Base, BSC, Corn

Basic Usage


import { createLombardSDK, Chain, DeployProtocol } from '@lombard.finance/sdk';
import { config } from './lib/lombard';
 
const sdk = createLombardSDK(config);
 
const withdraw = sdk.chain.evm.withdraw({
  sourceChain: Chain.ETHEREUM,
  protocol: DeployProtocol.Veda,
});
 
await withdraw.prepare({
  amount: '0.5',
});
 
// Check if approval is needed
if (withdraw.needsApproval) {
  await withdraw.approve();
}
 
const result = await withdraw.execute();

Status Flow


IDLE → NEEDS_APPROVAL → READY → COMPLETED

NEEDS_APPROVAL may be skipped if sufficient allowance exists.

Checking Pending Withdrawals


const pendingWithdrawals = await sdk.api.vaultWithdrawals('0x1234...');

Events


import { WithdrawEvent } from '@lombard.finance/sdk';
 
withdraw.on(WithdrawEvent.StatusChange, (status) => {
  console.log('Status:', status);
});
 
withdraw.on(WithdrawEvent.Completed, () => {
  console.log('Withdrawal queued!');
});
