# Accumulator Vaults

Accumulator Vaults turn a native ETH deposit into scheduled purchases of **PLAZM** or **ESHARE** on Base. Choose the token you want to accumulate and an open deposit cycle. A keeper submits the buys during that cycle's execution window.

| Vault              | Deposit    | Accumulate | Purchase route       |
| ------------------ | ---------- | ---------- | -------------------- |
| PLAZM Accumulator  | Native ETH | PLAZM      | ETH → ESHARE → PLAZM |
| ESHARE Accumulator | Native ETH | ESHARE     | ETH → ESHARE         |

The vaults hold the actual target tokens. Your deposit creates internal shares used to calculate your portion of the pooled tokens and remaining ETH; it does not mint a separate transferable receipt token.

## Getting started

1. Connect your wallet on **Base** and select PLAZM or ESHARE in the accumulator page.
2. Choose a cycle accepting deposits. Review its deposit deadline, execution length, buy interval, and swap fee.
3. Deposit native ETH, keeping some ETH in your wallet for network fees. No ERC-20 approval is needed for the deposit.
4. During execution, the vault spreads purchases across its remaining buy slots. It may also recycle held tokens through profitable arbitrage opportunities.
5. After settlement, claim your accumulated tokens. Any unspent ETH rolls into the next cycle.

Each token has one manager contract containing multiple numbered cycles. A new cycle is not a new contract deployment. Use the application to select a cycle; the two manager proxy addresses are listed under [Contract Addresses](/contract-addresses.md#accumulator-vaults).

Scheduled accumulation does not guarantee a profit. The number of tokens purchased depends on prices, liquidity, fees, and successful trade execution.

The application also includes a separate **LSteak accumulator** that accepts USDC and accumulates xl-LSTEAK. The native ETH deposit routes, fees, and settings described in this section apply to the PLAZM and ESHARE vaults.
