3xcalibur is an AMM based on Solidly with some key improvements, including voting mechanics, rewards, and emissions, built on Arbitrum.
3xcaliSwap is a Solidly fork built on Arbitrum with its native XCAL token emitted on a weekly basis and used to reward 3xcaliSwap LPs. XCAL holders can lock their tokens (up to maximum of 3.69 years) on the platform to receive veXCAL and participate in governance, which includes voting on which liquidity pools should receive XCAL emissions. 3xcaliSwap offers two kinds of pools: variable pools for uncorrelated assets and stable pools for pegged assets. Stable pools leverage the same Automated Market Maker (AMM) design as Curve's stableswap invariant and variable pools use the standard constant product AMM formula (like Uniswap V2). Key new features of 3xcaliSwap include MultiSwap, which allows traders to do a 1-to-n asset swap. The order will be directly routed through different pools to mitigate the gas fee as well as slippage. For example, users can swap 100 DAI for ETH, DPX, and GMX (users set the percentage distribution). Moreover, there is a Zap feature that allows traders to directly exchange a crypto asset for LP tokens, as well as MultiZap to exchange for a basket of whitelisted assets.
3xcaliSwap makes money through trading fees that are currently set at 0.27% for all swaps within a variable pool and 0.0369% for stable pools. veXCAL holders vote on which liquidity pools receive XCAL rewards, and pools earn proportionally to the voting power they accrue per week. veXCAL holders earn trading fees generated by the pools they voted for proportional to their voting power.
You earn XCAL emissions for providing liquidity on 3xcaliSwap. You can also stake XCAL to receive veXCAL and vote on pools to earn trading fees. veXCAL holders also earn bribe fees paid to the pools they voted for, as well as non-dilutive rebase emissions.
