This guide explains how to use the Ranger Earn SDK to deposit and withdraw funds between the vault’s idle account and strategies. The generic Voltr side uses:
  • getDepositStrategyInstructionAsync
  • getWithdrawStrategyInstructionAsync
The protocol side determines:
  • strategy address derivation
  • required ATAs and protocol accounts
  • any remaining accounts needed by the adaptor

​
Deposit To A Strategy

import { getDepositStrategyInstructionAsync } from "@voltr/vault-sdk";

const depositIx = await getDepositStrategyInstructionAsync({
  manager: managerSigner,
  vault: vaultAddress,
  vaultAssetMint: assetMintAddress,
  assetTokenProgram,
  strategy: strategyAddress,
  depositAmount: 1_000_000n,
  adaptorProgram,
  remainingAccounts: [
    // protocol-specific accounts
  ],
});

​
Withdraw From A Strategy

import { getWithdrawStrategyInstructionAsync } from "@voltr/vault-sdk";

const withdrawIx = await getWithdrawStrategyInstructionAsync({
  manager: managerSigner,
  vault: vaultAddress,
  vaultAssetMint: assetMintAddress,
  assetTokenProgram,
  strategy: strategyAddress,
  withdrawAmount: 500_000n,
  adaptorProgram,
  remainingAccounts: [
    // protocol-specific accounts
  ],
});

​
Operational Notes

  • ATAs created for strategy operations are usually a one-time manager-paid rent cost.
  • The manager should keep some idle vault liquidity for withdrawals.
  • Batch ATA setup and allocation instructions when possible.
  • Use the maintained adaptor repos for the exact account wiring.
