Finish links & Blinks
A finish link is one URL that lets anyone buy a coin’s final stretch from wherever you post it. On a phone it opens in their wallet; on X it can show up as a Blink with buy buttons right in the post.
The link
Every coin with a bounty, and every entry in a request, has a finish link:
corium.so/f/<coin, bounty or request>Get it with Copy finish link on a bounty card, or share the coin page. The page shows the coin, its curve, the bounties on it and three buy buttons: 0.1, 0.5 and 1 SOL, or any amount.
- On a phone, outside a wallet app, it offers to open itself in Phantom or Solflare, where you sign the buy.
- On a desktop with a wallet extension, it works like any page on corium.so.
- For pump.fun coins the buy is the finishing buy: pump.fun’s own buy, with the part past the 90% line recorded and locked until an hour after graduation.
- For a request,
?coin=<entry>on the end picks one of its entries. ?amount=0.5pre-fills the amount, and?r=yourcodeadds your referral.
Blinks
Corium serves Solana Actions, so wallets and apps that support Blinks turn a finish link into a card with buy buttons, inline, wherever it’s posted: on X with Phantom, Backpack or Dialect’s extension, and anywhere else that unfurls Actions.
| Shared link | Unfurls as |
|---|---|
corium.so/f/<id> | The finish card: a coin and its bounties, or a request’s leading entries |
corium.so/coin/<mint> | One coin, Corium or pump.fun |
corium.so/request/<id> | A request’s leading entries |
The mapping is published at corium.so/actions.json.
A Blink builds the same transaction as the finish page; your wallet shows it in full before you approve.
Telegram
In the Corium bot, /finish HDOG (a ticker) or /finish <pump.fun link> answers with the coin’s curve, its bounties, and buttons that open its finish page in your wallet with the amount filled in.
Links never trade on their own
A finish link, a Blink or a Telegram button only builds a transaction. Nothing happens until you approve it in your own wallet, and Corium never sees your keys.
