How it works
CoRelayer makes the transactions your app signs for its users gasless. We do the rest.

02 · Sponsoring
Your plan sets how many transactions, not how many users.
Builder and up · Agent Pro and Agent Fleet
The key stays on your server, never in a web page.
How sponsoring works →Every plan · 1 to 1,000 included, then 5 credits each
Compare plans →| Sponsor your users | Wallets you name | |
|---|---|---|
| Pays for | Every wallet your server runs | The wallets you list |
| How many | No limit on wallets. Your plan’s transactions are the limit. | 1 to 1,000 included, by plan; more at 5 credits each, up to 10,000 per account |
| You need | Your own server | A key your own code holds |
| Plans | Builder and up · Agent Pro and Agent Fleet | Every plan |
| Cost to add | Nothing | Included up to your plan’s number with no fee. Each wallet beyond it costs a small one-time fee. Removing one has no fee. |
The sponsor key is a secret, so it lives on your server.
How sponsoring works →03 · Control
Choose the contracts, per-user limits and price ceilings.
Every purchase and renewal carries a maximum price you sign. A renewal above your ceiling is skipped, not charged.
A sponsor key pays only for calls to the contracts you list. Anything else is refused.
Cap how many transactions any one user can send per day. Add a daily total for the key if you want one.
When your plan runs out, sending pauses. Pay-as-you-go spends only from a budget you set aside.
04 · Delivery
Your dashboard shows each transaction’s timeline, where it stopped and why.
If we can’t send a transaction, we ask your app to sign it again. The first one can then never go through, so nothing is sent twice.
The network runs each signed transaction once and refuses a repeat.
05 · Your users
No fee to approve: your plan covers it.
06 · The dashboard
Everything you need to run it, in one dashboard.
A timeline for each one, and the relayer that carried it.
Transactions per day, with a CSV export.
Create keys, choose their contracts and daily limits, revoke them any time.
Add or remove them from one screen.
Price ceilings, auto-renew and pay-as-you-go, all off until you turn them on.
Plan and price notices in the app, and a live event feed your server can follow.
07 · Build or buy
You could run this yourself. Here’s what that takes.
08 · FAQ
No. Your user’s signature covers every field, including our relayer. Any change would break it.
If it runs and fails, the network still charges its fee. We pay that fee, and the transaction counts against your plan. If it never runs, it doesn’t count. Either way, your dashboard shows where it stopped and why.
Every transaction step by step, your usage per day with a CSV export, your sponsor keys, the wallets you name, your spending limits and your notices.
Take the dashboard tour →It can delay or decline a transaction, never change or repeat it. You can check any relayer on chain before your user signs.

Connect a MultiversX wallet and pay a plan in USDC. Buying your plan is already a gasless transaction.
