Buybloom

Entry ——

Every buyback, a petal you can count.

Buybloom keeps a growth journal for coins that turn creator fees into buybacks and holder rewards. It reads the pool on Solana mainnet, logs every real buy, checks who qualifies for rewards, and lets a team publish a signed card of the wallets they control.

Plate I  ·  Reading the pool

A flower drawn from live buys on a Solana pool: each petal is one real buy, its length set by the buy's size. Tick marks on the ring are sells.

I Spring · how a buyback garden works

Fees are the seed. Buys are the bloom. The ledger is the proof.

  1. 01

    Fees are collected

    Every trade on a launchpad pays a small creator fee. That fee lands in a wallet the team controls, in SOL.

  2. 02

    Some buy the coin back

    A share of the fees buys the coin on its own pool. Each buy is a public transaction anyone can read.

  3. 03

    Holders share the rest

    The remainder is paid to holders above a threshold, pro rata to what they hold. The threshold decides who counts.

  4. 04

    The team signs its name

    The people who move the money publish their wallets and sign the list with those same keys. Buybloom checks the signature.

II Plate II · the buy ledger

Read the last 25 swaps on a pool, and press every buy.

Pick a trending coin or paste any mint. Buybloom finds its deepest pool on DexScreener, reads the newest transactions from mainnet, and works out who bought and who sold from the token balances before and after each one. Add the team's buyback wallet to read that wallet's own history instead and see only its buys.

III A year in the garden

Scroll through four seasons of a buyback, ring by ring.

  1. Spring. Launch week. Volume is high, fees are generous, the first ring is wide.
  2. Summer. Buybacks run every day. Each ring is a week of SOL turned into tokens off the market.
  3. Autumn. Volume cools, so rings get thinner. Honest gardens show this instead of hiding it.
  4. Winter. What is left is the record: every ring is a transaction anyone can look up.

Model Week 0 of 52 · ring width = weekly buyback

IV Summer · growth-ring model

What a buyback can and cannot move.

A constant-product model of the pool. Enter daily volume, the creator fee and the share that goes to buybacks; Buybloom compounds it week by week and shows how much supply is bought, and how far the price moves if nothing else trades. It is a model, not a forecast. Load a coin in the ledger and its live pool depth fills in.

Pool depth: default value. Load a coin in the ledger to use its live depth.

V Autumn · reward eligibility

Does this wallet qualify for the harvest?

Reads the wallet's real balance of the coin and the coin's live supply from mainnet, then applies a threshold rule. Connect a wallet and it fills itself in. The payout line is a model: it assumes rewards are split pro rata over the share of supply you say is eligible.

VI Winter · the public team card

Name the wallets. Show what they hold. Sign it with the key.

List the team wallets with their roles. Buybloom reads each one live: SOL balance, the coin held, and the last time it moved. Then the maintainer signs a digest of the card with their wallet. Anyone can paste the result into the verifier below and check the Ed25519 signature in their own browser.

VII Field notes · method

How each number is grown.

Buy or sell

For each transaction we sum token balances per owner before and after. If the signer's balance of the coin rises it is a buy, if it falls a sell. Pool vaults are ignored.

Δ = Σ post(owner, mint) − Σ pre(owner, mint)

Value

The SOL leg is the signer's lamport change plus wrapped-SOL change, fee added back. It is valued at today's SOL price from Jupiter.

usd = |ΔSOL + fee| × PSOL

Growth rings

Each week buys B = volume × fee × share × 7 into a pool x·y = k. Tokens out = y − k / (x + B). Volume decays by your weekly rate.

Δy = y − k ⁄ (x + B)

Eligibility

Balance across all token accounts of the mint, over live supply. Payout (model) = pool × your share ÷ eligible share.

pay = R × (b ⁄ S) ⁄ e

Signatures

The card is serialised in a fixed order, hashed with SHA-256, and the line that includes the digest is signed by the wallet. Verification is Ed25519 over those exact bytes.

VIII Questions from the garden gate

FAQ

Is any of this data invented?

No. The ledger, balances, supply and last-moved times are read from Solana mainnet when you press the button. The growth rings, the pinned year and the payout line are models, and they are labelled as models.

Why only 25 transactions?

Public RPC limits how fast transactions can be fetched. Buybloom reads the newest 25, four at a time, so it stays polite and quick. Run it again later to see the next set.

Does connecting a wallet let you move my funds?

No. Connecting shares your public key only. The single thing Buybloom ever asks your wallet for is a message signature on the team card, which costs nothing and cannot move funds.

Why does a buy show as "route"?

Aggregators and arbitrage bots pass through pools without the signer ending up with the coin. Those are counted separately so they do not inflate buy pressure.

Can a team fake its card?

A team can leave wallets off the list; nobody can stop that. What they cannot do is sign as a wallet they do not control. The signature proves the maintainer holds that key and approved that exact list.

Does Buybloom run the buybacks?

No. Buybloom never holds funds, never trades and never sends anything. It is a reading and checking tool for buybacks other people run.

A plain note on what is real

Live: pool swaps, balances, supply, wallet activity, SOL price, network almanac. Model: growth rings, the year sequence, reward payouts. Never: custody, trades, transfers, or private keys. Buybloom is an independent concept with no audits, partners or users claimed. It is not financial advice.
