v0.1.9 — predge_kalshi_attest + predge_wallet_attest

Two more signed-attestation tools — one ed25519 primitive, four verticals

• predge_kalshi_attest — ed25519-signed settled Kalshi market resolution (resolved, resolution yes|no, resolved_at) from Kalshi's public API, verifiable offline against the published key. Attests the market's own result, not trader data. Optional side → correct. Params: ticker, side.
• predge_wallet_attest — ed25519-signed wallet win/loss track record over resolved markets, verifiable offline — turns a self-reported win rate into signed proof. Params: address, window (7d|30d).

Now 19 tools (1 free + 18 paid), with four flagship signed attestations: Polymarket (predge_attest), sports (predge_sports_attest), Kalshi (predge_kalshi_attest), wallet track-record (predge_wallet_attest). Pays USDC per call on Base or Solana, no accounts.

Install

• npm: npx -y @predge/whale-data-mcp (also on the MCP Registry)
• Claude Desktop: download whale-data-mcp.mcpb below and open it.

v0.1.8 — predge_sports_attest (signed settled sports outcomes)

New: second flagship attestation — signed sports outcomes

predge_sports_attest — ed25519-signed settled game result (winner, final score, completed) sourced from ESPN, verifiable offline against Predge's published key at data.predge.io/.well-known/predge-attest.json. Optional winner (team abbr) → correct. Use it to settle bets, prove a track record, or ground a wager on tamper-evident truth. Unknown league / unfinished event → null, not charged.

Leagues: nba, wnba, nfl, college-football, mlb, nhl, mls, epl, champions-league, laliga.

17 tools total (1 free + 16 paid). Pays USDC per call on Base or Solana (PayAI facilitator, gasless). Bring your own funded key — it never leaves your machine.

Install

• npm: npx -y @predge/whale-data-mcp (also on the MCP Registry)
• Claude Desktop: download whale-data-mcp.mcpb below and open it.

v0.1.6 — Solana payment rail

MCP now pays on Base and/or Solana (previously Base-only). Set SOLANA_BUYER_SECRET (64-number JSON array or base58) to also pay on Solana — every paid route's 402 offers both networks and the client pays on whichever it holds a key for. The facilitator pays the network fee on either rail; the wallet needs USDC only. Base path unchanged (full backward compat).

One-click install (Claude Desktop / any MCPB host): download whale-data-mcp.mcpb below and open it — configure a Base key, a Solana key, or both.

v0.1.5 — Predge Whale Data MCP

Outcome-verified Polymarket whale intelligence as MCP tools — 16 tools (1 free discovery + 15 paid), including the flagship predge_attest (cryptographically signed resolved-outcome receipt). Pay-per-call over x402 (USDC on Base); bring your own funded key, it never leaves your machine.

One-click install (Claude Desktop / any MCPB host): download whale-data-mcp.mcpb below and open it — configure your Base-mainnet BUYER_PRIVATE_KEY (optional; the free discovery tool works without it) and MAX_PRICE_USD cap.

Or via npm: npx -y @predge/whale-data-mcp
