Abstract: A system and its methods are described for implementing meta-transactional interactions across one or more decentralized computing networks (“blockchains”) with a managed (“custodial”) wallet, satisfying an important need of lowering the barrier of entry for interacting with smart contracts across multiple blockchain networks. First, the method of encoding and storing a transactional request created by a user's managed account, representing an intention to broadcast the invocation of a specific function of a specific smart contract on one or more peer nodes of a specific blockchain. Then, calculating a cost for processing the encoded transaction within the specific blockchain via analysis including the value and type of cryptocurrency, complexity of transaction, historical trend of transaction fees, and analyses to eliminate the chance of loss due to insufficient transaction fees. Next, obtaining a payment from the user for the transfer of the amount to successfully process their queued transaction.

Abstract: A tape measure having a housing, a marking device for applying a mark to a surface to be marked, and a carriage member connected to a constant force spring for advancing a marking substance against a marking wheel configured for applying a mark to a surface to be measured and marked.

Abstract: An improved writing instrument for applying a marking material to a surface through use of at least one ball.

Abstract: A handheld device for cutting material, preferably linear material, such as ice pop sticks, building sticks, chalk sticks, dowels, plastic toy construction pieces, candy, and paper. The device having a cutting portion having a blade, a control portion controlling the cutting portion, and a base portion. The device configured, for instance by having a small hole into which the portion of the material to be cut is inserted, so as to prevent the user, such as a child, from being injured by contact with the blade.

Abstract: A stackable playing card having a non-slip coating applied to at least one of the peripheral edges of the playing card.

Abstract: The present invention is an improved construction toy set having a number of different structural elements which are configured for snapping together. These elements having key connectors configured for mating together, where integral locking indentations in the key connectors are configured for locking onto locking ridges provided on the adjacent structural element.

Abstract: A tape measure that incorporates a marking device for allowing an individual to measure and mark a wide variety of materials in a more efficient and economical manner, and for measuring and marking the beginning point of reference and the measured position point simultaneously. The tape measure has a housing, a coiled measuring tape, a tape tip, a chalk line, a chalk receptacle, a chalk line recharger, an activator, and an advancer. The chalk line is easily advanced and retracted for making marks at varying distances. The chalk is stored in a chalk storage receptacle that allows the chalk line to be re-chalked and is refillable for multiple uses. The activator allows the retractable chalk line to transfer a chalk substance from the chalk line to the surface to be measured and marked.

Abstract: A generally L-shaped spirit level vial having a vertical portion that is perpendicular to a horizontal portion. Both the vertical and horizontal portions fluidly interconnected so that the same, combined vial can be used either horizontally or vertically. Thus, only one of said vials need to be calibrated.

Abstract: A carpentry tool having a body, at least one bubble vial, a first marking indicia mark and a second marking indicia mark. The body generally parallelepipedal in shape, having a first end opposite a second end, a top level side opposite a bottom level side and a front face side opposite a back face side. The top level side having a measurement scale which sequentially increases in value from the first end to the second end. The bubble vial mounted within the level body, the bubble vial for indicating when a flat level side is oriented in a substantially horizontal position, the level bubble vial viewable through the front face. The marking indicia marks sixteen-inches or twenty-four-inches apart thereby signifying to a user the on-center measurements of wall studs.

Abstract: A level end cap for protecting a level body from damage. The level body having a first end. Defined within the first end is a plurality of holes therethrough. The end cap having an internal portion and an external portion. The external portion for protecting the end cap. The internal portion having extending therefrom an internal flange. Extending from the internal flange is a plurality of detents configured for extending through the plurality of holes in the body, thereby locking the end cap on the level body.
