Ideas from the plan
- A liquidity aggregator routing between the testnet's DMS/testUSDC and DMS/testWETH pools with slippage protection.
- A limit-order system on
pallet-intents: users post intents; a solver fills them against the DEX. - An MEV monitoring dashboard reading
TxCommitted/TxRevealedevents and alerting by webhook.
Bonus in judging for using commit–reveal.
What a builder should know
- The DEX's per-pool treasury account must exist before a pool can settle fees — the reason no swap settled until runtime 220. If you create a pool, fund its treasury.
- Swap fee ~0.00018 DMS; lending deposit ~0.00015 DMS on the testnet.
- Event names for MEV protection are
TxCommittedandTxRevealed(the explorer once listened for names that did not exist). - Everything is test value. The DeFi audit the mainnet gate requires has not been commissioned; you are building on unaudited code, which is what a testnet hackathon is for.
What you will find
Gaps. The first swap found a missing account; the first lending user will find something. Report it — a documented gap with a reproduction is worth points under documentation and is exactly the output the event exists to produce.
Status
The hackathon is designed and not announced; the faucet it needs is not deployed. The pallets are on the public testnet now, and nothing stops a team from building ahead of the event.
Based on TESTNET_HACKATHON_PLAN.md (Track 1), PALLET_REFERENCE.md and the runtime 220 notes.
