Throw a bottle

Free to throw. When someone finds it, you'll earn TIDE too — whether or not you attached a gift.

BDAG
Messages and gifts are stored on-chain: public and permanent. Do not include secrets or personal information. Bottles are written by other users and are not moderated.
A gift can't be recalled once thrown. It stays locked in the contract until someone finds the bottle, and is lost to you if nobody ever does. This is unaudited beta software — start small.

Trawl the depths

Trawl the ocean for a random eligible bottle. Find 3+ and you'll pull two per trip, find 7+ and it's three. If a bottle carries a gift, it comes with the catch — and every find earns you TIDE, the reward token, win or lose on the gift (bottles you threw yourself don't count).

Beta warnings & FAQ

Has this been audited?

No. The contracts are experimental and have not been independently audited. Bugs could cause you to lose funds, bottles, or TIDE. Only use amounts you are fully comfortable losing.

Who can read my message?

Everyone, forever. Everything on a public blockchain is readable, including the text of a bottle that has not been found yet — this page simply chooses not to show it early. Messages can't be edited or deleted. Never include secrets or personal details.

Can I get my gift back?

No. A gift attached to a bottle stays in the contract until someone finds that bottle. There is no cancel or refund, and if a bottle is never found its gift stays locked.

What might I see in other people's bottles?

Messages are written by anyone and are not moderated or removable, so you may come across content you find offensive or misleading.

Is finding a bottle really random?

Bottle selection uses on-chain block data as its randomness. That is fine for a game like this but is not tamper-proof against a validator or miner trying to bias the result. Don't treat outcomes as guaranteed or provably fair.

What is TIDE worth?

TIDE is a reward token for playing. It has no promised price, listing, or uses beyond what this game offers today (currently streak shields), and it may never be worth anything. Nothing here is financial advice.

Who controls the game?

An admin wallet can currently change the fee on found gifts (capped at 5% in the contract), the art renderer, and the TIDE reward settings. The contracts may also be replaced by new versions, and existing bottles, streaks or balances might not carry over.

Which chain is this on?

Chain 1404 (BlockDAG). Node operators on this chain have publicly disagreed about its history, and at least one RPC serves a diverged chain under the same chain ID. This page checks that the game contract exists on the network your wallet is using, but it can't tell you which chain is the canonical one.

Are the keepsake NFTs tradeable?

No. They are soulbound: each one stays in the wallet that found the bottle.
