Gamma Strategies (gamma)

​

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

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

Deployments

​

ABI

​

HypervisorABI

• 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

• 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

• 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)
