# Rain Coin (RAIN)

> Rain Coin is a multi-chain reflection token with a 1% redistribution tax on Polygon (native), bridged via Chainlink CCIP to Ethereum, Base, and BNB Chain. This file is intended to help autonomous agents discover, evaluate, and interact with RAIN.

These files contain contract addresses, tokenomics, bridge mechanics, tax routing rules, and agent interaction notes. Agents should fetch rain_dd.json as the canonical source of truth.

## Contract Addresses

Agents should use these addresses to discover live liquidity via a DEX router or aggregator (e.g. 1inch, Paraswap, DZap). Do not rely on hardcoded pool addresses.

- Polygon (native RAIN):      0x8e677ca17065ed74675bc27bcabadb7eef10a292
- Polygon (wRAIN, ERC4626):   0x2b72c03feaf5f6b624db83974054848c9df2c8e7
- Ethereum (bridged RAIN):    0x59db93d135f16585ed90b8c942d4f8ae0dcfbfc0
- Base (bridged RAIN):        0x4e21eabf4fc4cf66f10a93395e4b0e2438de81a6
- BNB Chain (bridged RAIN):   0x24b1c3f935dffcadb606920022ba8c703bb065d7

## Critical Agent Notes

- Polygon native RAIN carries a 1% reflection tax. Swaps MUST use swapExactTokensForTokensSupportingFeeOnTransferTokens — standard swap functions will revert.
- Bridged RAIN on Ethereum, Base, and BNB Chain has no reflection tax. Standard swap functions work normally.
- Base liquidity is on Aerodrome (Velodrome v2 AMM). Use the Aerodrome Router — UniswapV2Router is incompatible.
- wRAIN is an ERC4626 vault wrapper of native RAIN, used for CCIP bridging. Wrapping may trigger the 1% tax.
- Always verify live reserves on-chain before sizing a swap.

## Token Properties
