"The story that Toly tells that you can get your first 1000 users from Seeker is actually true. ...the average spend for these users is insane." -Magicblock co-founder @supermarioblock Shoutout to every Seeker 🖤

Just shipped the Identity Layer for @tendrdotbid powered by @sns - every tendr.bid user now gets a personal `.tendr.sol` identity at signup. Pick a handle, click Claim and you're done. No wallet popup, no signature. All fees sponsored by us!! Live on Devnet 🟢, Video Demo below 📹 Up until today, your wallet on tendr.bid showed up as a 44-character hash everywhere - leaderboards, profile pages, share cards. Trust signals don't really work when "the buyer" reads as `CRZUdacW…1JYv`. What we wanted was for procurement reputation to attach to a name humans can actually recognize - yours, and one that travels with you across every Solana app that resolves @SNS. So we built the identity layer. What changes for you: → First time you sign in, a one-screen modal asks you to pick a handle (3-20 characters). There's a Suggest button if you'd rather not think about it. → Click Claim. We mint `.tendr.sol` and assign ownership to your wallet on the spot. You don't sign anything, we cover the rent and sign the mint server-side. Same UX as receiving an airdrop. → From that moment your handle replaces your wallet hash everywhere - leaderboard, buyer + provider profile pages, RFP cards, milestone notes, the wallet popover, and the share card that unfurls when you paste a profile URL into @X. The privacy story is intact. Sealed-bid mode still hides bid contents (powered by @magicblock's TEE-gated Private Ephemeral Rollups), and private-bidder mode still hides bidders (powered by @cloak_ag's shielded UTXO pool). We deliberately never resolve `.tendr.sol` for the per-RFP ephemeral wallets used in private-bidder mode, those are anyways temporary per RFP wallets, not permanent identity. Bid Losers stay anon, Winners reputation get tagged to their `.tendr.sol` identity. A real thanks to the @SNS team, @ninjanovadotsol @SNSFai - incredibly responsive on Discord, helped us cut through several edge cases (devnet hierarchy, subdomain quirks) that would have otherwise been days of trial-and-error. The integration is meaningfully better for it. Please check it out below, and do share your feedback 👇✉️!!

Procurement on tendr.bid is now end-to-end private. When tendr.bid launched, providers could bid anonymously - bid contents were sealed in @magicblock's TEE-backed Private Ephemeral Rollup, and bid signers were per-RFP ephemerals unlinkable to the provider's main wallet. But the BUYER still appeared on chain at every step (RFP create, award, milestone accept, dispute), and the funding USDC moved through the buyer's main wallet. Half the marketplace was private; half was not. Now: the other half. → Anon buyer mode - Buyers can now toggle "Private buyer" at RFP creation. The buyer's main wallet does not appear on chain anywhere across the lifecycle (close-bidding, award, fund, accept-milestone, propose-dispute, cancel-with-penalty, refund). Public buyer reputation does NOT accumulate on these RFPs unless the buyer later opts in via Claim reputation. → End-to-end private funding via @cloak_ag - When the buyer funds the project, USDC flows: main wallet → Cloak shielded UTXO pool → per-RFP funding ephemeral → escrow. The on-chain trail is broken at the shielded hop, an observer scanning the escrow account can see "some funder deposited here" but cannot link the deposit back to the buyer's main wallet. The same shielded path also handles ephemeral SOL/USDC sweep + top-up, so leftover ephemeral balances can be reclaimed without re-introducing a link. → HD keychain primitive - One master signature per session unlocks every ephemeral the user will ever need across the app i.e. per-RFP buyer ephs, per-RFP bidder ephs, funding ephs, refund ephs, payout ephs. All derived deterministically via HKDF from a master seed. Cross-tab BroadcastChannel sync so opening a new tab doesn't re-prompt. No popup spam, no key management UI, no copy-paste of secrets. Web-app UX, on-chain anonymity. → Claim-based reputation, both sides - Anonymous RFPs and wins don't appear on public profiles by default. Users can CLAIM them post-completion via two new on-chain instructions (`attest_buyer_history` for buyers, `attest_win` for providers). Claim merges the reputation counters i.e. RFPs awarded, projects completed, USDC contracted, USDC released into the main wallet's public reputation in one atomic ix. For the first time on @solana, both sides of a procurement marketplace can be fully anonymous AND optionally surface reputation, on the same primitive shape. Genuine credit to @cloak_ag for making the shielded UTXO primitive accessible to a third-party app, without it, "anon buyer" and "end-to-end private funding" would not be real on-chain properties. And @magicblock's PER stays the load-bearing piece for sealed bid contents, the two primitives compose end-to-end now. The full Tendr privacy stack: - @cloak_ag shielded UTXO - bid SIGNERS, RFP buyer, and funding USDC all unlinkable to main wallets - HD keychain i.e. one master sign derives every per-RFP ephemeral; no per-action popups, no key management - @sns - recognizable identity (`.tendr.sol`) for when reputation enters the public surface via claim - @magicblock PER - bid CONTENTS sealed cryptographically until the window closes - @qvac Private AI - drafting + comparing bids without leaking commercial info to closed providers Three privacy primitives + a key-management primitive + an identity primitive. Privacy seals the bidding phase end-to-end; identity makes the claim-based reputation that comes out the other end portable and recognizable.
