Stake & burn

Creating a rollup commits a stake and burns a small percentage of it on creation. Both are governed by live chain parameters — always read them from rdk.params() before sizing a transaction rather than trusting the documented defaults.

The economics

• Creation stake — the amount you commit to register a rollup. Documented default: 10,000 QOR (minStakeForRollup, "10000000000" uqor).
• Creation burn — a fraction of the committed stake burned on creation. Documented default: 1% (rollupCreationBurnRate, "0.01").

The stake leaves your wallet on creation; the burn is taken from it, and the remainder is the net stake held against the rollup.

Read live values

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

const rdk = createRdkClient();
const params = await rdk.params();

console.log(params.minStakeForRollup);      // e.g. "10000000000" (uqor)
console.log(params.rollupCreationBurnRate); // e.g. "0.01"

Estimate the cost before submitting

estimateCreationCost computes the burn, the net stake, and the total leaving your wallet. Pass the live burn rate from rdk.params() for an exact figure.

import { estimateCreationCost, uqorToQor } from "@qorechain/rdk";

const cost = estimateCreationCost({
  stakeUqor: params.minStakeForRollup,
  burnRate: params.rollupCreationBurnRate,
});

console.log("stake:      ", uqorToQor(cost.stakeUqor), "QOR");
console.log("burn:       ", uqorToQor(cost.burnUqor), "QOR");
console.log("net stake:  ", uqorToQor(cost.netStakeUqor), "QOR");
console.log("total req'd:", uqorToQor(cost.totalRequiredUqor), "QOR");
console.log("burn rate:  ", cost.burnRate);

CreationCost fields, all in base uqor:

Field	Meaning
stakeUqor	The stake you commit
burnUqor	The amount burned on creation
netStakeUqor	Stake remaining after the burn
totalRequiredUqor	Total leaving your wallet (equal to the committed stake)
burnRate	The burn rate applied (decimal string)

Wire it into creation

Pass the stake when turning a config into a create message:

const createMsg = config.toCreateMsg(account.address, {
  stakeAmount: params.minStakeForRollup,
});
const res = await tx.createRollup(createMsg);

Show the estimated cost to the operator before broadcasting so there are no surprises. QOR has 10^6 base uqor units — use qorToUqor / uqorToQor to convert. See the Quickstart for the full create flow.
