Beam was developed by Eco, a funds firm backed by Web3 enterprise capital companies Andreessen Horowitz, Coinbase Ventures, Founders Fund, Lightspeed Enterprise Companions and Pantera Capital.
To create a Beam pockets, the consumer navigates to the applying’s web site, which generates a singular QR code representing an Optimism tackle. After this, customers can show their QR code to somebody who desires to ship them crypto. They’ll additionally click on the QR code to repeat the tackle in order that it may be despatched via electronic mail or on the spot messaging purposes. The net app might be accessed from a desktop or cell system.
To again up their pockets, customers should click on “save entry” and log into Twitter via its utility programming interface. They then click on “save entry” a second time and are prompted for a brand new password. After submitting the password, the account backup is full, and the consumer can then get better their account with their Twitter login and password if their system ever crashes.
In a dialog with Cointelegraph, Eco App and Beam CEO Andy Bromberg defined that the applying makes use of Web3Auth to again up accounts. Web3Auth is a type of new wallet technology that enables for seedless wallets to be created.
Bromberg mentioned the password serves as a backup shard for Web3Auth, which implies no hash of it’s ever saved on a centralized server, implying that neither Twitter nor Eco could make unauthorized transfers on a consumer’s behalf.
Regardless that Optimism’s native coin is Ether, Beam doesn’t require customers to personal ETH to pay fuel charges. As an alternative, fuel charges might be paid with the coin used within the switch. For instance, a consumer can ship $100 in USD Coin (USDC) for $0.50 in USDC.

To make this attainable, the pockets broadcasts two separate transactions. The primary transaction is the one the consumer requested, whereas the second transaction is a pledge to pay a third-party “paymaster” account if the paymaster agrees to pay fuel on the consumer’s behalf. Within the above instance utilizing USDC, the paymaster can pay $0.50 or much less value of ETH on behalf of the consumer and the consumer will concurrently pay $0.50 of USDC to the paymaster. Bromberg instructed Cointelegraph that paymasters can’t take extra charges than the consumer authorizes because the payment quantity is embedded within the signature used to authorize the transaction.
In accordance with Bromberg, utilizing paymasters has solely change into attainable since account abstraction was carried out in March, which allowed user-controlled pockets accounts to contain executable code for the primary time.
Beam may even be launched for Coinbase’s Base community when it officially launches in August. As soon as Base has formally launched, consumer balances on Base and Optimism might be added collectively and proven as one whole inside the Beam app, Bromberg acknowledged. When a buyer initiates a transaction, the Base and Optimism elements of the transaction might be broadcast concurrently on every community, making it appear to the consumer as if they’re interacting on a single community.
Due to this function, Bromberg referred to Beam as a “Superchain” pockets, implying that it’ll work together seamlessly throughout the OP Stack ecosystem.
Bromberg believes Beam would cut back awful consumer experiences with crypto wallets and permit unusual folks to undertake the know-how:
“We’ve abstracted away chains, addresses, charges — all of it — to make it so that standard folks can use it. I’ve been in crypto for 10 years now, and that is the primary noncustodial product that my dad and mom have ever been ready to make use of, and I’ve tried many occasions earlier than, and this did it. So we’re enthusiastic about it.”
Beam isn’t the one pockets app that goals to simplify crypto onboarding. Kresus pockets, launched on Could 11, permits customers to sign up with just an email address. On Could 8, Worldcoin launched a pockets that allows gas-free transactions for any customers that show their humanness via its protocol.
