8 incentive distribution listed for Spain
In ChainChoice’s published ranking order, from this category’s 8 providers: those whose terms exclude Spain are removed; naming Spain 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 SpainMerkl (Angle Labs)#1 globallyProvider states broad availability Offchain reward engine that publishes a per-recipient reward file for every merkle root it pushes to a named Distributor contract, opens a 1-2 hour onchain dispute window before rewards become claimable, and takes its 3% out of the deposited budget rather than on top of it.
Recomputable allocation — 9/10Budget control after publication — 8/10Incident and operator record — 8/10#2 for SpainSablier Airdrops (Merkle Lockups)#2 globallyProvider states broad availability A pure claim rail: the budget-holder uploads a CSV of [address, amount] pairs, Sablier builds a merkle tree, pins the full recipient list to IPFS and deploys an immutable-root campaign contract the buyer alone administers — it computes no allocation and publishes nothing about sybil defence, and as of 13 July 2026 Sablier Labs has stopped active development and funds maintenance only through June 2028.
Budget control after publication — 10/10Sybil defence in writing — 8/10#3 for SpainBoost (Rabbithole)#3 globallyProvider states broad availability Onchain incentive protocol from Boost Studios Inc (formerly RabbitHole) where the budget sits in a named ManagedBudget contract the buyer owns and eligibility is set as inspectable, buyer-configured filters and onchain allowlists — but no reward file, no dispute window, no appeal path and no security page are published anywhere in its 104-page documentation corpus.
Budget control after publication — 8/10Sybil defence in writing — 8/10#4 for SpainStreamflow#4 globallyLists Europe; Spain not individually verified Solana-only distribution rail that takes the buyer's own CSV, publishes a merkle root on chain via an open-sourced SDK and IDL, and hands the campaign creator per-recipient cancellation, clawback and admin transfer — with the semantics documented in a package README rather than in the help centre a budget-holder would read.
Budget control after publication — 7/10Sybil defence in writing — 7/10#5 for SpainHedgey#5 globallyProvider states broad availability A free, self-service onchain distribution rail — the buyer uploads the recipient list as a CSV, Hedgey builds the merkle tree and the tokens sit in one published contract the buyer alone controls; it computes no allocation and leaves sybil defence to the buyer's own whitelist CSV plus, for streamed claims, a documented option to claw back unstreamed tokens claimed by bots and airdrop farmers discovered post-claim; no live surface it is evaluated on — homepage, docs, app or HedgeyPro — mentions the ~$45m ClaimCampaigns.sol drain of April 2024, though the change of operator to Anchorage Digital IS disclosed in a site-wide banner.
Budget control after publication — 8/10Sybil defence in writing — 7/10#6 for SpainGalxe Quest / Business+#6 globallyProvider states broad availability The volume incumbent: a no-code campaign platform where the budget-holder deposits reward tokens into Galxe's own dashboard, the allocation is computed in a closed backend and released by a Galxe-held signer key, and the sybil filter is a proprietary detector sold as a $999-$1,699/month Business+ toggle.
Incident and operator record — 7/10Sybil defence in writing — 6/10#7 for SpainLayer3#7 globallyProvider states broad availability No-code Activation builder that deploys a per-campaign onchain escrow the budget-holder funds directly and Layer3 never custodies — but every payout is released by an off-chain EIP-712 signature from a Layer3 signer role that also sets, per mint, a rake deducted from the recipient's reward.
Incident and operator record — 6/10Sybil defence in writing — 6/10#8 for SpainZealy#8 globallyProvider states broad availability Quest and leaderboard engine (ex-Crew3, operated by Freyja Labs, Orleans) that computes who won inside a closed backend, custodies the buyer's USDC as an off-chain balance it never documents how to withdraw, and hands token rewards back to the buyer to distribute manually.
Incident and operator record — 5/10Sybil defence in writing — 5/10
