8 SocialFi listed for Portugal
In ChainChoice’s published ranking order, from this category’s 8 providers: those whose terms exclude Portugal are removed; naming Portugal or a region that covers it counts the same, and those whose terms do not state it come last. Each chip names the basis: a dated check, a region listing, or the provider's own claim.
#1 for PortugalNostr#1 globallyProvider states broad availability A public-domain protocol with no company in it: your identity is a secp256k1 keypair, your follow list is a kind-3 event you signed yourself, and any relay that will carry you is enough — but nothing in the spec obliges a relay to keep your data and nothing in it pays you.
Handle and graph custody — 10/10Who outranks my keys — 10/10Exit path and somewhere to go — 9/10#2 for Portugalfriend.tech#2 globallyProvider states broad availability An abandoned-by-its-market but still-maintained and structurally immutable Base social-key market: owner() renounced on six of eight contracts, a 5% creator fee that no one on earth can change, a complete reimplementation surface published on its own about page — and a Terms of Service that still reserves the right to revoke your username at sole discretion.
Handle and graph custody — 9/10Earnings waterfall — 9/10Who outranks my keys — 8/10#3 for PortugalLens Protocol#3 globallyProvider states broad availability Onchain social protocol on Lens Chain where the username is an ERC-721 and the follow graph is a public contract anyone can read without an API key — but one externally-owned account holds the upgrade beacon over both, and is also the fee recipient.
Handle and graph custody — 9/10Exit path and somewhere to go — 8/10#4 for PortugalBluesky / AT Protocol#4 globallyProvider states broad availability A federated, non-blockchain social protocol whose exit path is the best-documented in the category — two independent PDS implementations, two independent relays and a step-by-step migration lifecycle — bought at the price of a DID directory operated solely by Bluesky Social PBC and no creator earnings rail of any kind.
Exit path and somewhere to go — 9/10Handle and graph custody — 6/10#5 for PortugalFarcaster#5 globallyProvider states broad availability Onchain identity registry on OP Mainnet plus an open-source offchain message network: the fid and its recovery address are permissionless contract state, the follow graph is user-signed data replicated across nodes anyone can run, and the default @handle is an offchain name the operator says it can revoke at will.
Exit path and somewhere to go — 8/10Handle and graph custody — 7/10#6 for PortugalTowns Protocol#6 globallyProvider states broad availability Onchain group chat where the community itself is an ERC-721 you can sell — the Space is a real token I called on Base, but the handle and the member graph are end-to-end-encrypted stream metadata on a DAO-approved node set, and the fee split beneath the protocol's 10% top-line take is published nowhere.
Handle and graph custody — 6/10Earnings waterfall — 4/10#7 for PortugalZora#7 globallyProvider states broad availability A Base-native social app where every profile and every post becomes a tradeable coin, with the pool's most completely itemised fee waterfall (1% split five ways) attached to a profile record that lives entirely in Zora's own hosted API.
Earnings waterfall — 6/10Who outranks my keys — 3/10#8 for PortugalParagraph#8 globallyProvider states broad availability A hosted publishing and newsletter platform, now marketed as an AI publishing agent, whose handle and subscriber graph live entirely in a vendor database — with a subscriber CSV export that three first-party statements put on every plan and a fourth withholds from Free, and a live post-coin rail on Base whose fee split it documents nowhere.
