Super AI Chain ships Uniswap V2, Uniswap V3, the Universal Router (v1.6.0), and Permit2 — all deployed from the official audited bytecode. The pair/pool init code hashes are byte-for-byte identical to Ethereum mainnet, so any Uniswap interface fork, SDK, router, or aggregator works by configuring the chain ID and addresses — no SDK hash patching required.

The Universal Router is the canonical swap entrypoint: it aggregates V2 + V3 liquidity in a single execute call and supports gasless ERC20 approvals via Permit2 (sign once, no per-swap approve transaction).

The Universal Router needs two init-code hashes to compute pair/pool addresses on the fly. They are part of the deployment record (not addresses, so they are not in the table above):

Swap with the SDK (Universal Router + Permit2)​

@superaichain/sdk wraps the whole flow — best-route quoting (single hop or two hops via WSUP), the one-time Permit2 approval, the EIP-712 signature, and the execute call:

import { SuperClient } from '@superaichain/sdk';
import { parseUnits } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
const client = SuperClient.testnet({ account });
const { stables } = client.addresses;

// Inspect the route the SDK picked (V2/V3, single or multi-hop).
const route = await client.swap.routeExactIn({
  tokenIn: stables.WSUP,
  tokenOut: stables.tUSDT,
  amountIn: parseUnits('1', 18),
});
console.log(route.label, route.amountOut); // e.g. "V3(3000)" 998312...

// Execute via the Universal Router. The SDK approves Permit2 + signs once,
// reuses the allowance afterwards, and applies 0.5% slippage by default.
const { hash, amountOutMin } = await client.swap.exactInUniversal({
  tokenIn: stables.WSUP,
  tokenOut: stables.tUSDT,
  amountIn: parseUnits('1', 18),
  slippageBps: 50,
});
console.log('swap tx', hash, 'min out', amountOutMin);

Python (superaichain) mirrors the same flow:

from superaichain import SuperClient

client = SuperClient.testnet(private_key=PRIVATE_KEY)
stables = client.addresses["stables"]
res = client.swap.exact_in_universal(
    stables["WSUP"], stables["tUSDT"], 10**18, slippage_bps=50
)
print(res["hash"], res["amountOutMin"])
