Terms of service

CoRelayer delivers MultiversX transactions on your behalf. You build and sign a transaction; we add a relayer signature, pay the network fee in EGLD and broadcast it. We do not decide what your transaction does and we cannot change it.

We do not take custody of your funds or your keys at any point, and there is no step in this service that grants us authority over your balances.

An account is a MultiversX address. Whoever controls that address controls the account, including its credits and its plan. We cannot restore access to an address whose key is lost, and we will not transfer an account between addresses.

An account may authorise other addresses to send transactions against its plan. Those addresses keep their own keys; authorising them is a decision you make on chain and can reverse on chain.

On a plan that includes sponsoring, an account may also create sponsor keys. A sponsor key lets your server send transactions for any sender, paid from your plan, within the contracts and daily limits you set for the key. Keep it secret: whoever holds it can spend your plan until you revoke it.

A plan includes a number of Relay Units per period. Usage inside that allowance is covered by the plan. When the allowance is used up, the account stops relaying unless pay-as-you-go is enabled. Pay-as-you-go spends only a budget you moved into escrow in advance. On a plan, its price per transaction is fixed when you buy the plan and does not change for the prepaid block; on Agent Metered it follows the tariff, and you can sign a per-transaction ceiling for it (0 means no ceiling).

A transaction that runs and fails is billed; one that never runs is not. A transaction that executes on chain counts as usage whether it succeeds or fails: the network charges the relayer its fee either way. A transaction that never executes is released and not billed.

Unused allowance does not carry into the next period. The one exception is an upgrade, which moves the unused part of the current period’s allowance into the new plan’s first period, once.

Payments are made in the token the contract is configured to accept and become credits on your account. Credits are not refundable — this is set out in full on the payments page, and the checkout you sign states the amount and the ceiling before you approve.

Do not use the service to relay transactions that are illegal where you are, that attack the network or another user, or that attempt to drain relayer funds through the allowance for free actions.

We may decline to relay a specific transaction, and we may suspend an account that is doing the above. Where we suspend an account we will say why.

We publish availability and latency once we have measured them, and only then. We do not offer a contractual availability figure, and we will not quote one before we have the measurements to support it.

Plans that name a delivery class — shared pool, priority lane, dedicated relayers — describe how transactions are routed, not a percentage we promise.

The chain decides whether a transaction executes and what it does. We are responsible for delivering what you signed; we are not responsible for the outcome of a transaction you chose to sign, for the state of the network, or for the behaviour of contracts you interact with.

Price changes follow the tariff rules on the pricing page: an increase is announced on chain 48 hours ahead, a decrease is immediate, and a period you have paid for keeps its price. Changes to this document will be dated here, and a material change will be announced in the app before it applies.
