An inbox with a toll · Robinhood Chain

Get heard.
Or get paid.

Anyone can reach you on Copperline. They just lock a small deposit with their message. Reply, and it goes back to them. Ignore it, and it's yours.

SCROLL
How it works
01 / send

A stranger wants
your time.

They write the message and see your price before they send it.

02 / lock

The deposit
gets locked.

It sits in the Copperline contract, not with us and not with you. A reply window starts, 7 days by default.

03 / reply

You reply.
It goes back.

Answer inside the window and the full deposit returns to the sender. For them, being heard was free.

04 / or keep

You don't.
It's yours.

Let the window close and the deposit is released to you. Spam finally pays for the time it takes.

If people want your time

Your attention finally has a price.

  • Spam pays you. Mass DMs either get filtered by the deposit or leave money behind.
  • No guilt. If you can't get to something, the sender is compensated for the wait.
  • One link. Put it in your bio and stop writing "DMs closed".
If you're reaching out

Serious senders risk nothing.

  • Get a reply, get it back. Your deposit only costs you if you're ignored.
  • Stand out. A message with a deposit gets opened before the noise.
  • A clear signal. The window tells you exactly how long to wait.
Sealed until settled

Locked in the contract.
Not with us.

The deposit waits on-chain until you reply or the window closes. Nobody else can touch it.

Illustration. A higher price usually means fewer messages. The point is that the ones that arrive are worth opening.

Built for

Anyone with more inbox
than hours.

Founders

Pitches, intros and partnership asks, sorted by who's serious.

KOLs

Promo requests that pay for the time they take.

Investors

Cold decks with skin in the game.

Recruiters

Candidates who mean it, not copy-paste blasts.

Creators

Fans who want a real reply, on fair terms.

The rules

Short,
and on-chain.

The contract settles every message the same way. Nobody can step in and change the outcome.

  1. A reply is a signed message from the recipient's wallet, sent inside the window.
  2. Replies refund in full. The sender gets back exactly what they locked.
  3. Lapsed messages release to the recipient once the window closes. Anyone can trigger it.
  4. Prices are public. Senders see the deposit and the window before sending.
  5. Messages are encrypted to the recipient. The contract only knows a message exists.

FAQ

Questions,
answered.

Isn't this just paid DMs?

Paid DMs charge the sender either way. On Copperline the sender only pays if they're ignored. A reply makes it free.

Can't I just reply "ok" to everything?

You can, and the deposit goes back. That's fine: the sender wanted an answer and got one. You never earn by replying, only by not replying.

Who holds the money?

The Copperline contract does, until the message is settled. Nobody else can move it.

What is $COPPERLINE?

The community token of the Copperline project on Robinhood Chain. The contract address will be posted here and on our X account at launch. Ignore any address you see anywhere else.

Is the inbox live?

Not yet. Copperline is in its first phase: brand, community and token. The inbox is in development.
