Our plan is to build an MVP for a newly approved use case: advertisers creating campaigns with set deliverables and prices for targeted influencers, all managed through a Soroban smart contract. Following this, we'll launch a full platform testnet and partner with ecosystem players for off-ramp exchanges. The final step involves launching on the mainnet and migrating our user base, with seamless onboarding from Telegram using Passkey login on Stellar.
Advertisers can make deposits on Soroban smart contracts and set up deliverables with prices (content creation, post, repost).
Influencers with verified social metrics and sufficient criteria can view available proposals from advertisers with instant fixed payouts in USDC on Stellar after completion.
Influencers publish the content and provide proof links to the smart contract. B4B algorithms verify the sufficiency of the submitted task.
Influencers unlock their payment within 24 hours on their Stellar wallet.
Advertisers can view a dashboard with results and links from influencers, as well as their budget spending on integrations.
Integrate the new functionality with the current version of the platform, including influencers' reputation data.
Cover the functional autotests and launch full testnet.
Integrate off-ramp USDC withdrawal (with API partners—OffRampMeDaddy) to USD for Web2 influencers from their Stellar wallet.
Conduct final audits, prepare a monitoring dashboard, migrate the database, and launch on Stellar mainnet with full functionality.
Integrate mainnet Passkey verification with the Telegram mini-app for Social Score checking and influencer onboarding
Maybe in the future, but not in this submission
$90.0K
After the launch:
Each brand confirms monthly deposits of $5,000-$10,000
50 brands engage in monthly content creation
$1M+ Annual Recurring Revenue (ARR) achieved within one year
1,000 influencers/KOLs onboarded through Passkey and Telegram Mini app with Influence Score
Viral growth of influencers and companies on the platform
Concept and Go-To-Market (GTM) strategy approved and prepared for scaling
Influencers
We currently offer invite-only access to attract high-quality content creators. This approach enables us to build a community of genuine Web3 influencers—not mere shillers—who are eager for meaningful interactions with each other.
Our influencers now fulfill 70% of advertisers' requests.
Strategies for expanding our influencers/KOLs network:
After successfully completing an advertising campaign, an influencer typically brings in 2-3 other influencers.
Telegram mini-app for user incentivization with future implementation of Passkey auth https://t.me/B4BinfluenceBot/InfluenceScore?startapp=ref_djx8KO Users can measure their influence score and increase it by inviting influencers to the platform. We aim to onboard approximately 10,000 Telegram influencers with new Web2 audiences into the Web3 space.
Collaborations with major Web3 ecosystems and attracting engaged influencers in the space
Influencer marketing on the B4B platform to engage more users
Advertisers
We have successful case studies: https://docsend.com/view/yuz9srtbugarfxx9
After collaborating with Web3 leaders and analyzing our initial cases, we've refined our product. We're now developing an enhanced model for KOL engagement, which has already secured $150,000 in pre-orders.
Strategies for expanding our influencers/KOLs network:
B2B sales via connections and partners (50 pre-commitments after the last two conferences)
Referral program (influencers often recommend us to brands unprompted)
AMA sessions with marketing leaders and projects in the Web3 marketing sphere

TLDR: We have completed the Proof of Concept (PoC) version, which has successfully launched on Stellar testnet with Soroban smart-contract implementation and Passkey sign-up on the platform.
The fully functional testnet has been successfully launched. The B4B Community of Influencers in Telegram has expressed enthusiasm for the passkey integration, providing positive feedback.
We have just launched our application as a Telegram Mini App to simplify onboarding for Telegram influencers. This app calculates their Influence Score and allows them to invite friends to grow their influence.
The goal: Develop the new proved functionality and launch the final MVP of B4B.app on the Stellar testnet. Implement core functionality allowing advertisers to set up deliverables for influencers, with interactions facilitated through Soroban Smart Contract.

Brief description:
Advertisers create deposits on smart contracts for content creation campaigns.
They set up tasks (post, repost, content, etc.) for content creation, specifying fixed payments and target metrics for influencers' profiles.
Influencers meeting the target criteria gain access to create content and receive instant payment upon completion via smart contract.
Influencers publish content, submit proof links, and unlock payment.
The payment is released from the smart contract 24 hours after ad completion.

Total Budget: $30,000
We plan to integrate the new implemented MVP functionality with the core architecture of the platform to prepare for mainnet launch and full database migration. The Advertisers will be able to create the content on the budget with fixed deliverables or choose the direct integrations with the influencers. The main payment logic works with USDC via Soroban Smart-contract. We'll implement comprehensive autotest coverage for core functionalities and initiate a testnet launch for our supportive influencer community.

Web2 influencers need to convert their USDC payments received on their Stellar wallet to USD in their bank accounts, complying with all KYC requirements. We'll integrate Stellar services to enable Web2 influencers to access these features on our platform. For the integration we plan to collaborate with ecosystem project RampMeDaddy via API.
