Building on @Arc - send USDC like a link. no wallet. no gas.
solo builder 🟢

[apollo440.base.eth @0xApollo440]

Just submitted LinkCash to the @circle Grants Program.

Built around one simple idea:

Sending USDC should feel as easy as sending a message.

No wallets
No seed phrases
No crypto confusion
Now we wait ⚡

[apollo440.base.eth @0xApollo440]

Sending crypto to normal people still sucks

You send someone USDC and suddenly they need to:
install a wallet,
save a seed phrase,
buy gas,
learn what a network is,
and pray they don’t lose everything.

Most people give up before they even receive the money.

So we built #LinkCash

You send a simple link.
The other person opens it, logs in with Google or X, and instantly gets a wallet created in the background.

No extensions.
No wallet setup.
No crypto knowledge needed.

Just open the link and claim the USDC.

Here’s how it works:

• You lock USDC in a smart contract on @arc
• LinkCash creates a claim link
• Recipient signs in socially
• Relayer pays the gas
• Funds arrive on-chain instantly

That’s it.

We already have a live MVP on Arc testnet:
https://t.co/Fx8YN5impW

Smart contracts are deployed.
Backend works.
Frontend works.
People are already testing it.

Next things we’re building:

bulk payouts
payroll via CSV
Telegram & Discord claiming
fiat onramps
merchant payments
optional KYC for larger transfers
yield on unclaimed balances

The goal is simple:

Make receiving stablecoins feel as easy as opening a message

4 hours this morning. Fixed 1 bug. Claude suggested the wrong import. 3 times. I trusted it every time.

My cofounder is an AI that lies with absolute confidence. I still ship faster than when I coded alone.

Solo building in 2026 hits different.

[apollo440.base.eth @0xApollo440]

@theBlurryface0 @arc From "never built anything" on May 14 to shipping a full domain app in 3 weeks. That's the part people should pay attention to

[apollo440.base.eth @0xApollo440]

@Defi_Princess_1 @base @baseapp @Based_Africa @buildonbase @coinbase Everyone says the next billion won't care about the tech. Then why do 90% of crypto apps still make you set up a wallet on step one?

[apollo440.base.eth @0xApollo440]

@mysucesstory Back from the dead. Now make them regret the 2 year wai

@R7gen @circle @Ripple @PayPal Yeah. You click a link, sign in with Google, money's there. Built on @arc where gas is paid in USDC so you don't pay anything. https://t.co/GGeikmlf96

Mastercard solved settlement between institutions.
@circle USDC. @Ripple RLUSD. @PayPal PYUSD.
6 stablecoins.
8 chains.
Multiple banks.
Now who solves sending $20 to your friend without making them install a wallet first?

[Mastercard @Mastercard]

Today, Mastercard is announcing plans to expand settlement capabilities to include stablecoin, intraday, holiday, and weekend options, giving partners more choice in how and when transactions are settled. That means we’re:

✅ Enabling greater choice to settle in fiat or regulated stablecoins

✅ Improving liquidity management for time sensitive, cross border flows

We’re supporting settlement with @Circle’s USDC, @Paxos-issued stablecoins including USDG,USDP and @PayPal’s PYUSD, @Ripple’s RLUSD and @SoFi’s SoFiUSD across a range of supported blockchain networks including Arbitrum, @Coinbase’s Base, @CantonNetwork’s Canton, Ethereum, @0xPolygon, @Solana, @Tempo and XRPL. ARQ Finance, CBW Bank, @crossriverbank, @Lead_Bank and @Nuvei will be among the first to support.

@ashcotXBT @circle @Ripple @PayPal That's the gap nobody's filling yet

[apollo440.base.eth @0xApollo440]

GENIUS Act passed.
Banks finally moving from theory to real implementation.
But the person who actually receives the USDC still hits the same wall.
Wallet. Seed phrase
Right chain
Gas
That last mile for normal humans is still completely broken.

[Circle @circle]

Since the GENIUS Act passed, conversations with banks and financial institutions shifted from theory to implementation.

"How do we actually leverage this technology?"

@Siraaaaaaajatt @arc top secret 😀

[apollo440.base.eth @0xApollo440]

Some days you ship features. Some days you eat lunch by a lake with a sticky note that says ARC
Both count

[apollo440.base.eth @0xApollo440]

@AlexandrB27 @Ignyte_AE @arc @circle Some of them just want to have a picture like yours and make a post on Twitter to gain some mindshare. 😁

[apollo440.base.eth @0xApollo440]

@AlexandrB27 @Ignyte_AE @arc @circle There is lot of applicants like this. I think nobody gonna check them

[apollo440.base.eth @0xApollo440]

@Iziedking Nigeria has the demand. Arc has the rails. This is the match that matters.

[apollo440.base.eth @0xApollo440]

@Defi_Princess_1 @arc From spectator to builder. That's the shift that changes everything

[apollo440.base.eth @0xApollo440]

@CryptoAsuran @arc How was the integration? Curious if the sample covers the UCW side or just external wallets

[apollo440.base.eth @0xApollo440]

@temmmy612 Sent a wire transfer last month. Three days. In 2026. The joke writes itself

[apollo440.base.eth @0xApollo440]

@heyfrens1 @circle The hardware wallet point is the one nobody mentions. Doesn't matter if your chain is PQ if the signer isn't

[apollo440.base.eth @0xApollo440]

@ItsRoboki Open source perp DEX reference on Arc. This is the kind of infra that makes the whole ecosystem stronger. Respect.

[apollo440.base.eth @0xApollo440]

@0xStrache Discord username as identity is a smart move. The fewer steps between "I want to pay you" and "done" the better.
