How it works # They sign. You pay one plan. It covers the fee. CoRelayer makes the transactions your app signs for its users gasless. We do the rest. Get started Read the docs Building an AI agent? Start here → Illustration: Your app signs , CoRelayer pays the network fee in EGLD, and you pay one plan in USDC. 01 · Step by step ## Three steps, one transaction The technical version → - Step 01 / 03 ### Your app signs With the wallet it keeps for your user. One signature per action. The transaction is theirs, from their own address. - Step 02 / 03 ### Your plan covers the network fee A CoRelayer relayer adds its signature, pays the fee in EGLD and sends the transaction to MultiversX. - Step 03 / 03 ### You pay one plan In USDC, 30 days at a time. Each transaction counts against your plan, or your pay-as-you-go budget if you turn it on. 02 · Sponsoring ## Pay for the wallets you run, or the ones you name Your plan sets how many transactions, not how many users. - Sponsor your users ### One key pays for every wallet you run Your server holds one sponsor key. It pays for every wallet your app runs on your server: embedded wallets, games, custodial apps, agent platforms. You choose which contracts it covers and how many transactions each user may send per day. Builder and up · Agent Pro and Agent Fleet The key stays on your server, never in a web page. How sponsoring works → - Wallets you name ### Pay for wallets you know List the wallets you know in advance: your bots, your devices, your scripts. Your plan pays for them. Remove one any time, with no fee. Every plan · 1 to 1,000 included, then 5 credits each Compare plans → ### Choosing between them 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 ## You stay in control Choose the contracts, per-user limits and price ceilings. - ### Price ceilings Every purchase and renewal carries a maximum price you sign. A renewal above your ceiling is skipped, not charged. - ### Contracts you choose A sponsor key pays only for calls to the contracts you list. Anything else is refused. - ### Per-user limits Cap how many transactions any one user can send per day. Add a daily total for the key if you want one. - ### Your call at the limit When your plan runs out, sending pauses. Pay-as-you-go spends only from a budget you set aside. 04 · Delivery ## If something goes wrong Illustration: a signed transaction. The signature covers every field, so a relayer can’t change it, and the network refuses the same transaction a second time. - ### You see it Your dashboard shows each transaction’s timeline, where it stopped and why. - ### Rarely, a second signature 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. - ### Never twice The network runs each signed transaction once and refuses a repeat. How delivery works → 05 · Your users ## What your users see No fee to approve: your plan covers it. 06 · The dashboard ## What you get in the app Everything you need to run it, in one dashboard. - ### Every transaction, step by step A timeline for each one, and the relayer that carried it. - ### Usage you can account for Transactions per day, with a CSV export. - ### Sponsor keys Create keys, choose their contracts and daily limits, revoke them any time. - ### Wallets you name Add or remove them from one screen. - ### Spending limits Price ceilings, auto-renew and pay-as-you-go, all off until you turn them on. - ### Notices, as they happen Plan and price notices in the app, and a live event feed your server can follow. 07 · Build or buy ## The fee is tiny. Running relayers isn’t. You could run this yourself. Here’s what that takes. ### On your own - A funded relayer wallet in every shard - Watching balances and topping them up - Retries that must never send twice - Someone on call to keep it running ### With CoRelayer - One plan in USDC - Relayers in every shard, kept funded - Delivery handled for you - Every step on record in your dashboard 08 · FAQ ## Questions buyers ask Can CoRelayer change my users’ transactions? No. Your user’s signature covers every field, including our relayer. Any change would break it. What happens if a transaction fails? 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. What do I see in the dashboard? 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 → What if a relayer is slow or declines? It can delay or decline a transaction, never change or repeat it. You can check any relayer on chain before your user signs.
