Preset profiles

The RDK ships five first-class preset profiles. Each one returns a RollupConfigBuilder pre-filled with documented, sensible defaults that you can override field by field. The presets are the fastest way to a valid configuration.

import { presets } from "@qorechain/rdk";

const config = presets.defi({ rollupId: "my-defi-rollup" });

Comparison

Profile	Settlement	Sequencer	DA	Block time	Gas model	VM	Max tx/block
defi	zk (snark)	dedicated	native	500 ms	eip1559	EVM	10,000
gaming	based	based	native	200 ms	flat	custom	50,000
nft	optimistic	dedicated	celestia	2,000 ms	standard	CosmWasm	5,000
enterprise	based	based	native	1,000 ms	subsidized	EVM	20,000
custom	optimistic	dedicated	native	1,000 ms	standard	EVM	10,000

The nft preset targets Celestia DA, which is selectable but not yet active on the network. It validates with a non-fatal warning; switch its da to native for live submission today. See Data availability.

When to use each

• defi — high-value, latency-sensitive financial apps that want fast, cryptographic finality. zk-SNARK settlement with EIP-1559 fees on the EVM.
• gaming — high-throughput, low-latency apps. Based settlement and a based sequencer with flat gas on a custom VM, tuned for many small transactions per block.
• nft — general-purpose minting and marketplaces on CosmWasm with optimistic settlement and a simple standard gas model.
• enterprise — permissioned-friendly EVM rollups with subsidized gas and based settlement for predictable, host-coupled finality.
• custom — a fully parameterized starting point with every field documented; override freely.

Overriding fields

Use .set({ ... }) to override any field; the compatibility matrix is enforced when you validate or build.

const config = presets.defi({ rollupId: "my-defi-rollup" }).set({
  blockTimeMs: 400,
  maxTxPerBlock: 8000,
});

config.validate(); // throws if the overrides break the matrix

QCAI-assisted profile suggestion

If you are not sure which profile fits, describe your app in plain language and let the QCAI-assisted advisory recommend a starting point. It calls a JSON-RPC advisory method and normalizes the answer to one of the five profiles. If the service is unreachable or returns something unrecognized, it falls back to defi and reports source: "fallback", so it is always safe to call.

import { createRdkClient } from "@qorechain/rdk";

const rdk = createRdkClient();

const suggestion = await rdk.suggestProfile("high-frequency DeFi DEX");
console.log(suggestion.profile); // e.g. "defi"
console.log(suggestion.source);  // "advisory" or "fallback"

// Then build from the suggested profile:
const config = presets[suggestion.profile]({ rollupId: "my-rollup" });

You can also override the fallback profile with { fallback: "gaming" }.

The advisory is a starting point, not a guarantee — always review the resulting configuration and validate it before creating the rollup.
