The portal-ponder repository contains three bounded examples. Each one uses the public Portal and a public RPC by default, so you can run it without keys. Clone the repository once:

​
Euler subgraph port

examples/euler-subgraph ports the core of the Euler V2 subgraph to Ponder. It covers factory discovery, five EVault action events, readContract, derived values, and GraphQL.
The repository’s verification result is 39 vaults, 887 action rows, and 900 vault status rows. Run npm run summary after the backfill completes to check the result.

​
Euler multichain

examples/euler-multichain configures Ethereum, Base, and Arbitrum in one app. Each chain has a factory() source and handlers for Deposit, Withdraw, Borrow, Repay, and Liquidate.
The current bounded ranges return 39 vaults and 887 action events on Ethereum. The Base and Arbitrum demo ranges complete but contain no matching rows. Set your own ranges before using them as data-volume examples.

​
All source types

examples/uniswap-portal exercises the source paths in one Ethereum app:
  • Uniswap V3 Swap logs with transaction receipts
  • Uniswap V2 Router call traces
  • a block source with an interval of 1,000
  • transactions to and from WETH through an account source
The repository’s verification query returns 848 swaps, 1,676 router calls, 3 block ticks, and 1,871 WETH account transactions for its default range.
These are functional examples, not benchmarks. Their public endpoints are shared and can run at different speeds under load.
