factory
Track dynamically created contracts.
factory(config: FactoryConfig): Factory
address: Factory contract address or array of addresses (required)event: Factory creation event ABI (required)parameter: Extract child address (event) => string (required)database: Factory database instance (required)
Example:
import { factory, factorySqliteDatabase } from "@subsquid/pipes/evm";
const factoryInstance = factory({
address: "0x1f98431c8ad98523631ae4a59f267346ea31f984",
event: factoryAbi.events.PoolCreated,
parameter: "pool",
database: factorySqliteDatabase({ path: "./pools.sqlite" }),
});
const factoryInstance = factory({
address: [
"0x1f98431c8ad98523631ae4a59f267346ea31f984", // Uniswap V3
"0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f", // Uniswap V2
],
event: factoryAbi.events.PoolCreated,
parameter: "pool",
database: factorySqliteDatabase({ path: "./pools.sqlite" }),
});
The address parameter now supports arrays to track contracts from multiple factories simultaneously.
Bugfix: factory.address now correctly represents the factory contract address (not the child contract address). This ensures accurate identification of which factory created each contract.
factorySqliteDatabase
Create SQLite factory database.
factorySqliteDatabase(config: { path: string }): FactoryDatabase
import { factorySqliteDatabase } from "@subsquid/pipes/evm";
const db = factorySqliteDatabase({ path: "./factories.sqlite" });
No longer requires await - returns the database instance synchronously.
portalSqliteCache
Create SQLite cache for Portal responses.
portalSqliteCache(config: { path: string }): PortalCache
import { portalSqliteCache } from "@subsquid/pipes/portal-cache/node";
const cache = portalSqliteCache({ path: "./cache.sqlite" });
Import from @subsquid/pipes/portal-cache/node instead of @subsquid/pipes/portal-cache.
commonAbis
Pre-defined ABIs for standard contracts.
import { commonAbis } from "@subsquid/pipes/evm";
// ERC20 Events
commonAbis.erc20.events.Transfer;
commonAbis.erc20.events.Approval;
// ERC20 Functions
commonAbis.erc20.functions.transfer;
commonAbis.erc20.functions.approve;
commonAbis.erc20.functions.name;
commonAbis.erc20.functions.symbol;
commonAbis.erc20.functions.decimals;
commonAbis.erc20.functions.balanceOf;
commonAbis.erc20.functions.totalSupply;
commonAbis.erc20.functions.allowance;
Currently, only ERC20 ABIs are available in commonAbis. For ERC721 and other token standards, use @subsquid/evm-typegen to generate custom ABIs from your contract JSON files.
