# Gamma Strategies (gamma)

> Active concentrated liquidity management protocol. Manages Uniswap V3, Algebra, and other CL DEX positions with automated rebalancing via Hypervisor vaults.

Active concentrated liquidity management protocol. Manages Uniswap V3, Algebra, and other CL DEX positions with automated rebalancing via Hypervisor vaults.

| Fact | Value |
| - | - |
| Category | Yield and vaults |
| Family | none |
| Namespace | `Gamma` on ethereum, polygon |
| Chains | ethereum, polygon |

## What it offers

* **deposit**: Deposit token pair into Gamma Hypervisor via UniProxy
* **withdraw**: Withdraw liquidity from Hypervisor

## Notes

* Each Hypervisor is a vault for a specific token pair
* Deposit via UniProxy (not directly on Hypervisor) - UniProxy handles deposit ratio enforcement
* Use getDepositAmount() to find correct token1 amount for your token0 deposit
* The uint256\[4] minIn/minAmounts array provides slippage protection (use zeros for no limit)
* Approve both token0 and token1 to UniProxy before depositing
* The Ethereum UniProxy is an older deployment; its `deposit` has no `minIn`: call it through `UniProxyLegacyABI`, `deposit(deposit0, deposit1, to, pos)`.

## Its names in a program

On Ethereum, `Gamma` is a namespace: its contracts need no import.

```ts theme={null}
function main() {
  // Ethereum's uniProxy, `0xF5BFA20F4A77933fEE0C7bB7F39E7642A070d599`.
  require(Gamma.UniProxyLegacy != 0);
}
```

## Deployments

| Chain | Contract | Address | In a program |
| - | - | - | - |
| [Ethereum](https://docs.eco.com/sauce-sdk/reference/chains/ethereum.md) | uniProxy | `0xF5BFA20F4A77933fEE0C7bB7F39E7642A070d599` | `Gamma.UniProxyLegacy` |
| [Polygon](https://docs.eco.com/sauce-sdk/reference/chains/polygon.md) | uniProxy | `0xA42d55074869491D60Ac05490376B74cF19B00e6` | `Gamma.UniProxy` |

## ABI

### `HypervisorABI`

`import HypervisorABI from "./protocols/gamma/HypervisorABI.json";`

* `withdraw(uint256 shares, address to, address from, uint256[4] minAmounts) returns (uint256 amount0, uint256 amount1)`
* `balanceOf(address account) view returns (uint256)`
* `totalSupply() view returns (uint256)`
* `getTotalAmounts() view returns (uint256 total0, uint256 total1)`

### `UniProxyABI`

`import UniProxyABI from "./protocols/gamma/UniProxyABI.json";` Speaks for: uniProxy.

* `deposit(uint256 deposit0, uint256 deposit1, address to, address pos, uint256[4] minIn) returns (uint256 shares)`
* `getDepositAmount(address pos, address token, uint256 _deposit) view returns (uint256 amountStart, uint256 amountEnd)`

### `UniProxyLegacyABI`

`import UniProxyLegacyABI from "./protocols/gamma/UniProxyLegacyABI.json";` Speaks for: uniProxy.

* `deposit(uint256 deposit0, uint256 deposit1, address to, address pos) returns (uint256 shares)`
* `getDepositAmount(address pos, address token, uint256 _deposit) view returns (uint256 amountStart, uint256 amountEnd)`
