ABI fragments

Raw viem-style Abi arrays for the SYMMIO contracts, for consumers who call viem directly (bypassing the SDK’s typed actions). Use these as an escape hatch — the typed actions are recommended for everything the SDK already covers.

Import

import { accountLayerAbi, instantLayerAbi, symmioAbi } from "@symmio/trading-core";

Each is a readonly Abi array exported straight from the versioned src/abi/v0.8.5/ files.

Available fragments

The current version is v0.8.5 — sourced from @symm-io/perps-core. When the SDK ships a second version, ABIs will route through a version-aware registry; today they are directly re-exported.

Usage — viem readContract

import { createPublicClient, http } from "viem";
import { hyperEvm } from "viem/chains";
import { accountLayerAbi } from "@symmio/trading-core";
 
const client = createPublicClient({ chain: hyperEvm, transport: http() });
 
const result = await client.readContract({
  address: "0x…",
  abi: accountLayerAbi,
  functionName: "getSubAccountsCountOfUser",
  args: [user],
});

Usage — viem writeContract

import { walletClient } from "./client";
import { symmioAbi } from "@symmio/trading-core";
 
const hash = await walletClient.writeContract({
  address: "0x…",
  abi: symmioAbi,
  functionName: "allocate",
  args: [subAccount, amount],
});

Pair with Config.getChainConfig(chainId).addresses (see Addresses) for the deployment-specific address.

When to reach for the ABI vs typed actions

Prefer the typed action when one exists:

• Typed actions run through Config.getClient / getWalletClient, so chain switching and wallet routing already work.
• They wrap responses in typed shapes (Quote, Market, LockedValues) with 18-decimal-wei bigint.
• They surface SDK errors (SymmError / SymmApiError) instead of raw viem errors when the failure is config-level.

Reach for the ABI directly when:

• The function isn’t wrapped by the SDK yet.
• You want raw viem semantics (e.g. multicall batches, custom overrides).
• You’re building diagnostics that need untouched ABI-level output.

• Config — client resolvers to pair the ABI with.
• AccountLayer / InstantLayer / SYMMIO Contract — typed actions built on top.
