♻️ RΞRANGE

Quickstart

Rerange can be integrated through the generated Wagmi package, raw ABIs, or Solidity interfaces. The public package is @rerange/wagmi; it exports generated reads/writes, ABI, and deployment metadata.

Install

npm install @rerange/wagmi @wagmi/core @wagmi/connectors viem

Use viem for ABI encoding, ticks, and any app-specific price math. Use @rerange/wagmi for the contract surface.

import { createConfig, http } from "@wagmi/core";
import { base } from "viem/chains";
import { encodeAbiParameters, parseUnits, zeroAddress } from "viem";
import {
  readRerangeHubPreviewOpen,
  v3AdapterAddressByChainId,
} from "@rerange/wagmi";

const config = createConfig({
  chains: [base],
  transports: {
    [base.id]: http(),
  },
});

const adapterConfig = encodeAbiParameters(
  [
    {
      type: "tuple",
      components: [
        { name: "pool", type: "address" },
        { name: "fee", type: "uint24" },
        { name: "twapWindow", type: "uint32" },
        { name: "maxTwapDeviation", type: "uint24" },
        { name: "maxTickDeviation", type: "uint24" },
        { name: "slippageBps", type: "uint16" },
      ],
    },
  ],
  [
    {
      pool: "0x6c561b446416e1a00e8e93e221854d6ea4171372",
      fee: 3000,
      twapWindow: 0,
      maxTwapDeviation: 20,
      maxTickDeviation: 0,
      slippageBps: 30,
    },
  ],
);

const params = {
  vault: zeroAddress,
  adapter: v3AdapterAddressByChainId[base.id],
  token0: "0x4200000000000000000000000000000000000006",
  token1: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
  capital: parseUnits("1", 18),
  isSell: true,
  targetTick: -195000,
  triggerTicks: 300,
  adapterConfig,
  referrer: zeroAddress,
  keepBalancesInVault: false,
  unwrapOut: false,
} as const;

const preview = await readRerangeHubPreviewOpen(config, {
  chainId: base.id,
  args: ["0x1111111111111111111111111111111111111111", params],
});

console.log(preview.lowerTick, preview.upperTick, preview.market.currentTick);

Apps should convert user prices into ticks before constructing params. Keep token order canonical for the pool: token0 is the lower-address pool token, not necessarily the user’s source token.

Create An Order

After building params as above, connect a wallet and submit the open transaction.

import { connect, createConfig, http, switchChain } from "@wagmi/core";
import { injected } from "@wagmi/connectors";
import { base } from "viem/chains";
import { writeRerangeHubOpen } from "@rerange/wagmi";

const config = createConfig({
  chains: [base],
  connectors: [injected()],
  transports: {
    [base.id]: http(),
  },
});

const { accounts } = await connect(config, {
  connector: injected(),
});
await switchChain(config, { chainId: base.id });

const hash = await writeRerangeHubOpen(config, {
  chainId: base.id,
  account: accounts[0],
  args: [params],
});

Before calling open, approve the hub for the source token top-up or pre-fund the resolved vault. You can also use open2 with Permit2.

Read Orders And Vaults

import {
  readRerangeHubGetOrderKey,
  readRerangeHubGetOrderState,
  readRerangeHubPredictVault,
  readRerangeHubVaultOrderCount,
  readRerangeHubVaults,
} from "@rerange/wagmi";

const owner = "0x1111111111111111111111111111111111111111";
const vaultCount = await readRerangeHubVaults(config, {
  chainId: base.id,
  args: [owner],
});

const vault = await readRerangeHubPredictVault(config, {
  chainId: base.id,
  args: [owner, vaultCount - 1n],
});

const orderCount = await readRerangeHubVaultOrderCount(config, {
  chainId: base.id,
  args: [vault],
});

const orderKey = await readRerangeHubGetOrderKey(config, {
  chainId: base.id,
  args: [vault, orderCount - 1n],
});

const state = await readRerangeHubGetOrderState(config, {
  chainId: base.id,
  args: [orderKey],
});

getOrderState(orderKey) is the canonical read for status, range, liquidity, progress, fees, and market tick.

Direct Contract Flow

If you call contracts directly:

  1. Resolve or create a vault with predictVault(owner, vaultIndex) or createVault().
  2. Encode adapter config.
  3. Call previewOpen(owner, params) to validate range and get current market context.
  4. Approve the hub for source token top-up, pre-fund the vault, or use open2 with Permit2.
  5. Call open(params).
  6. Derive orderKey = keccak256(abi.encode(vault, orderIndex)), or read it from OrderOpened.
  7. Read state with getOrderState(orderKey).

CreateOrderParams

Field Description
vault Existing vault address, or zero address to resolve/create the next vault for the caller.
adapter Allowed adapter address, usually the public Uniswap v3 adapter.
token0, token1 Canonical pool token order, not user input order.
capital Source amount in raw token units.
isSell true when source is token0, false when source is token1.
targetTick Fixed execution target in pool ticks.
triggerTicks Max tick distance from target for the live sliding range.
adapterConfig Venue-specific config, such as Uniswap v3 pool, fee, TWAP, tick drift, and slippage settings.
referrer Address receiving configured non-target-asset fee share, or zero address.
keepBalancesInVault Keep final balances in vault instead of withdrawing on close.
unwrapOut Unwrap WETH output to native ETH where supported by close flow.

Uniswap v3 Adapter Config

The public v3 config tuple is:

Field Type Typical value
pool address Uniswap v3 pool address
fee uint24 500, 3000, or 10000
twapWindow uint32 0 or an integration-defined window
maxTwapDeviation uint24 20
maxTickDeviation uint24 0 unless you explicitly allow drift
slippageBps uint16 30
